![shiiiiiio;, with some wliitisli j)()IIi7iosc pntclies al)oiit tlic shoulders ; seen from ill front it is ifreyisli, witli a dark median stripe. No s])ine on front margin. Sentellnm with four ratlier strong bristles. A})do}ne)i blackish. Le(jf;: Front femur ochreons with a darker ring at liase and another before tip, extreme tij) also dark ; tibia with base and tij) dark, and a dark ring before the middle. Middle femur in tv])e oclmeons, with extreme tip and a preapical ring brown, in other specimens mainly dark brown. Hind femur blackish, more or less ochreons on basal half, especially in Middle and hind tibiae yellowish, with dark brown tips. All tarsi pale ochreons, segments with dark tips. Front femur armed with about six strong spines beneath, first close to base and others rather widely spaced. Female claws each with a small tooth on inner side, \\ inqs hyaline, anterior veins not very dark. 7?r, more than twice as long as 7?i, and ending above or scarcely beyond level of tip of Cu^. Base of median fork just ses.sile. Halteres yellowish. Wing-length 1*7 mm. Manna : Tan, type o and $, 20.xi.lf)26 (Judd). Savaii: Safime, rain forest above 2,000 ft., 2 8.V.1924 (Bryan). Also damaged specimens from Tntuila (Pago Pago), 16.iv.1924 (Bryan), and Tntnila, 760-900 ft., 18.iv. (Kellers). By the armature of the front femora, this species seems related to B. australiensis Kieff. (New South Wales). The leg-markings vary in distinctness. CHIRONOMIDAE. No species of this family had been recorded from Samoa until 1926, when I described four marine s])ecies obtained by Buxton and Hopkins, including the remarkable new genus Po)ifo»iyia. In addition to these, examples of ten other species—seven from the Buxton and Hopkins collection and three from the Bishop Museum—are before me. Probably more species could have been discovered in the taro swamps near A])ia, but it is not likely that Samoa has a large Chironomid fauna because of the paucity of suitable breeding grounds. Of the fourteen species obtained, ten appear to be endemic, and only one of the remaining four has so far been found in Fiji, this being a widely-distri¬ buted species. The most interesting of the new species described here belongs to Thalassomyia, the fourth marine genus of Chironomidae to be found in this area. Tavo grou})S of sea-midges remain unre])resented in the Samoan fauna as known at present: Caniptocladim, and the Tcluudogeton-HaUrytus group. It is ])robable that future collecting will reveal the ])resence of the.se also.](https://iiif.wellcomecollection.org/image/b29809071_0038.jp2/full/800%2C/0/default.jpg)
