setose along its margin. Harpes divided, the main limb stout, 

 crowned apically with a dense group of very stout, chitinous spines. 

 The minor limb nearly as long, slender, somewhat falcate, apex 

 acute. Harpagones stout, longer than harpes, terminating in a 

 rather blunt, chitinous spur. Unci indeterminate. 



Stegomyia notoscripta Skuse. Genitalia, male. Basal clasp 

 segment stout, conical, tapering gradually to a rounded apex. 

 Apical segment rather stout, very short and bearing a long, slender 

 terminal spine. Claspette apparently wanting. Harpes, basal por- 

 tion naked except at the extreme base; apical part curved, falcate, 

 tapering to an acute point. Harpagones stout, terminating in a 

 stout, recurved spine. Unci slender, approximate, with a broadly 

 roimded apex. Setaceous lobes moderate, each with three or four 

 stout, chitinous spines. 



The genitalia in this species are peculiar in that the basal clasp 

 segments are thickly clothed with stout, broad scales. Steg- 

 omyia fasciata is evidenth'- the type of this genus, and 

 as its genitalia diverge remarkably from the above described form, 

 the latter should be referred to a new genus. It is much closer 

 related to Culicada than to Stegomyia and might well be referred 

 to that genus. 



Pneumaculex signifer Coq. Genitalia, male. Basal clasp seg- 

 ment stout, tapering gradually to a narrowly rounded apex. Termi- 

 nal segment rather stout, slightly curved, somewhat expanded at 

 the base and with a long, rather stout apical spine, the latter with 

 a stout apical tooth and four or five more slender, ventral teeth. 

 Claspette a rather conspicuous basal lobe bearing several stout, 

 chitinous spines. There are also two stout, chitinous spines arising 

 direct from the venter of the basal clasp segment near the apex of 

 the claspette. Harpes moderate, somewhat inflated near the 

 middle and tapering to three stout, chitinous spines. Harpagones 

 divided, composed of two stout, recurved, chitinous processes, the 

 posterior limb larger than the atiterior. Unci approximate, fused, 

 swollen at the base, slightly contracted posteriorly and with three 

 rather small subapical chitinous spines, posterior margin broadly 

 rounded. Setaceous lobes apparent!}- absent. [PI. 17, fig. 2] 



Protoculex serratus Theo. Genitalia, male. Basal clasp seg- 

 ment rather stout, slightly curved, narrowly truncate apically. 

 Terminal clasp segment rather slender, slightly swollen near the 

 middle and abruptly curved near the tip and with a long, slender 

 apical spine. Claspette a distinct, nearly free basal bladclike pro- 

 cess bearing on its outer edge near the middle a stout, irregularly 

 curv'ed, acute chitinous spine. At the apex of the basal clasp seg- 

 ment there is a long, subacute, bladelike process. Basal portion 

 of harpes enlarged, somewhat triangular, apical portion smooth, 

 irregularly curved, with a rounded apex. Harpagones stout, 

 strongly curved, with an acute, recurved apical spine. Unci 

 approximate, outer margin curved, tapering to an acute point. 

 Setaceous lobes moderate, each slightly divided and bearing about 

 four long, ^tout, chitinous spines. [Fig. 4 and pi. 18, fig. i]
