Female head.— Two specimens (I. 17164 & 1.9993) show 

 the palpi and proboscis well. The proboscis is about 2*7 mm. in 

 length, and distinctly shorter than the abdomen (which in 1. 17164 

 is 3 - 2 mm. long). The palpi are one-fifth as long as the proboscis, 

 and apparently two-segmented, the second being 1"7 times as long 

 as the .first. A third specimen (H. 468) is considerably shorter 

 (proboscis, 2 mm. ; abdomen, 2*2 mm), and the second segment of 

 the palpi seems relatively somewhat shorter; this rnay possibly 

 represent another species. Another specimen (1.20561) shows a 

 portion of an antenna, and in this the second segment of the 

 j^alpi is also shorter, 1*5 times the length of the first.

[All X 37, except/, which is X 22.] 



a, hypopygium, I. 17069, showing several short bristles at the tip of the 

 •clasper ; 7, seventh sternite with> terminal row of bristles, b, approximate 

 shape of clasper in end view (in all the specimens examined the clasper was 

 seen edgewise, or in section only), c, hypopygium, I. 9404 ; small specimen. 

 d, hypopygium, I. 8986 ; claspers apparently more slender apically than in 

 a and c, but this is probably owing to the position of preservation ; 7, 8, seventh 

 and eighth abdominal segments, e, hypopygium, 1. 10074, showing traces of 

 internal organs, perhaps tenth sternites ; 9 ?, perhaps ninth tergite. /, mouth- 

 parts and antenna?, I. 9629, showing hairs, etc. (see also photograph) ; the 

 hypopygium of this specimen is like that of 1. 10074. g, tip of proboscis 

 and palpus, I. 8986. h, tip of palpus, 1. 10074 ; the tip of the proboscis is 

 broken off.
