Althoiiyii the, species lias been recoi'ded liitherto only from West Africa, Ingram and jMacfie have already suggested that it may be much more widely s])read, and that species described by I\i(4Ter from s])ecimens from Tunis and the Seychelles may be the same. In West Africa the larvae were found ])v Ingram to be semi-aquatic and to prey on mos(]iiito larvae. .47. Lasiohelea samoensis, sj). n. $. Head dark. Eyes very finely ])ubescent, the hairs scarcely half as long as diameter of facets, and not very dense. Rostrum very short, scarcely half as long as vertical diameter of head. Antennae dark brown, rather short ; first eight flagellar segments disc-like, considerably broader than long ; next two not more than twice as long as broad, last three rather longer, the terminal one the longest but still less than three times as long as broad. Thorax dull blackish, mesonotiim with rather coarse but not very dense dark brown pubescence. Abdomen with integument and pubescence dull blackish. IjCgs entirely dark brown. First segment of hind tarsi fully tlu’ee times as long as second. All tarsi with rather numerous hair-like scales. ]Ihh//,s almost as in L. lefauui; macrotrichia not very dense, leaving distinct bare lines along each side of the veins ; above base of cubital fork there are about three rows of macrotrichia between cubitus and lower branch of media, and three between branches of media.

The species of Lasiohelea are so similar in all parts of the tropics that it is difficult to suggest the exact afUnities of this new species. It seems, however, to have more resemblance to A. stimidans (de Meij.), of the Malayan region, than to A. townsinUensis (Taylor), of Queensland. From A. stvmulans it differs in its smaller size, shorter antennae and dark mesonotal pid)escence.
