inner ones. Tergum slender, greatly extended beyond the harpes 

 and harpagones. Lobes of eighth segment stout, slightly taper- 

 ing, obliquely pointed, naked processes. 



Anopheles maculipennis Meig. Genitalia, male. Basal clasp 

 segment stout, evenly rounded. Terminal clasp segment slender, 

 arcuate, bearing a short, stout apical spine. Claspette a moder- 

 ately developed basal lobe bearing two, long chitinous spines. 

 There is also a large, chitinous spine at the inner apical third of the 

 basal lobe. Harpes slender, fused, with two apical groups of three 

 stout spines. Harpagones, basal portion irregularly triangular, 

 apical portion consisting of an outer long, slender, fingerlike process 

 and a pair of inner chitinous, acute spines, the inner one of the pair 

 being longer than the other. Tergum slender, extending beyond 

 the harpes and harpagones. Lobes of eighth segment slightly 

 capitate with naked, acute tips. 



Cellia albipes Theo. Genitalia, male. Basal clasp segment 

 rather slender, apex broadly rounded. Terminal clasp segment 

 long, slender, arcuate, slightly enlarged at both extremities, the 

 apex bearing a rather stout spine. Claspette represented by a 

 conspicuous basal lobe and a larger one near the middle, the former 

 bearing one and the latter two large chitinous spines with acute, 

 recurved tips. Harpes long, slender, fused, apex broadly rounded, 

 expanded. Harpagones with base broadly expanded, some- 

 what triangular, the apical portion bearing a pair of stout, 

 slightly curved, chitinous processes with acute tips. Tergum 

 slender, greatly extended beyond the harpes. Lobes of eighth 

 segment indeterminate. [PI. 4, fig. i] 



Cycloleppteron grabhamii Theo. Genitalia, male. Basal clasp 

 segment stout, with a rather broadly rounded apex. Terminal 

 clasp segment long, slender, arcuate, base and apex slightly 

 enlarged, the latter bearing a short, stout apical spur. Claspette 

 a bilobed basal elevation on the first clasp segment, each lobe bear- 

 ing a large, chitinous spine with an acute, recurved tip The basal 

 clasp segment also bears a prominent chitinous spine at the internal 

 third. Harpes very slender, approximate, each with a pair of 

 acute, spinelike processes at its apex. Harpagones, basal portion 

 broad, triangular, apical part a slender, acute, chitinous spine. At 

 the extreme base there is a tubercular elevation bearing a con- 

 spicuous spine, possibly a lobe of the harpagones, though it may 

 prove to be one of several minor basal spine-bearing elevations on 

 the first clasp segment.' Tergum large, fused and extending 

 beyond the harpes and the harpagones. Lobes of eighth segment 

 slender, smooth, fingerlike, with apex rounded. [PI. 4, lig. 2] 



Nyssorhynchus jamesii Theo. Genitalia, male. Basal clasp 

 segment stout with a rather broadly rounded apex. Terminal 

 clasp segment long, slender, arcuate, base and terminal portion 

 slightly enlarged, the latter bearing a rather small, stout terminal 

 spine. Claspette apparently represented by a single stout, curved 

 ventral spine. Harpes very slender, approximate, each with about 

 three divergent, acute processes. Basal portion of harpagones 

 brofirllv rounded and bearing at the apex a stout, fingerlike, chit-
