﻿356 R. NEWSTEAD — ON THE CHARACTERISTICS OF CLOSSINA 



good, as the general colour of the abdomen, though a shade brighter, is most 

 like thax of G. longipennis. I append below a further description of G. austeni. 



Head buff, relatively narrow, posterior surface usually faintly greenish grey ; 

 frontal stripe varying between warm buff and dusky red-brown. Third segment 

 of antennae buff, with the apical two-thirds, or apex only, infuscated. Palpi 

 ochreous buff, infuscated distally. Proboscis bulb ochraceous buff, with or 

 without median infuscation. 



Thorax dusky buff, tawny ochraceous or faintly isabella-coloured ; the 

 usual dark brown or blackish markings forming a more or less distinct, broad 

 bilateral stripe which, under a low magnification, is seen to be composed of 

 three well-marked areas : a small but well-defined triangular or roughly cres- 

 centic spot in front, near the humeral callus ; and two much larger spots or 

 areas divided by the narrow pale transverse suture and outlined laterally by a 

 very clear and sharply defined margin. The two dark narrow admedian stripes 

 are often present, and when continued behind the transverse suture their ends 

 diverge ; in some instances the stripes unite and form a relatively broad median 

 one ; or they may be entirely wanting, especially in the males. 



Legs pale ochreous buff ; front femora often with a faint infuscated patch on 

 the inner surface distally ; hairs on the front, middle and hind coxae all black ; 

 tips of last two segments of front and middle tarsi very narrowly darker, but 

 sometimes the dark colour is absent in the former ; all the segments of the hind 

 tarsi dark, but the last two segments are often darker than the rest. 



Abdomen : dorsum bright ochraceous, reddish ochreous or yellowish buff ; 

 second segment usually with a small dark brown blotch near the anterior lateral 

 angle ; third and fourth segments with a larger dark brown blotch (sometimes 

 quite indistinct or altogether wanting) not reaching to the hind margin ; fifth 

 and sixth segments more qi* less uniformly infuscated, but paler medially, or 

 with interrupted bands ; in some examples the second to the sixth segments, 

 inclusive, have clove-brown or dark brown, interrupted, bands, similar to those 

 in G. longipalpis, though not so clearly defined : seventh segment in female 

 uniformly dark brown or clove-brown. 



Wings without any marked infuscations. 



Genital armature of the male (fig. 1). Superior claspers (sc) united by the 

 dorsal spinose membrane and fused medially as in G. morsitans and other 

 members of the " morsitans-gvouip " ; form resembling somewhat the outline of 

 a human foot in minature, outer lateral projection strongly produced and 

 narrowly rounded, but without a blunt tooth-like process as in G. longipalpis ; 

 distal margin between the outer lateral projection or heel -like extension and 

 the medial lobes furnished with a fringe of short stiff spines, which unite 

 with the series on the inner lateral margin, where they gradually lengthen 

 and proximally form a more or less compact group ; median lobes (ml) 

 relatively very large and broadly rounded, forming the toe-like extension of 

 the clasper ; the long marginal hairs arranged in two pairs distally, the single 

 sub-terminal one projecting backwards. Long hairs of the editum (e) scarcely 

 reaching the lateral hairs of the superior claspers. Harpes (h) pointed and 

 narrowly triangular in outline dorsally, but ventrally there is an outwardly 

 curved process (see dotted line, fig. 1 h) ; outer lateral surface clothed with
