blackish with a wide V — form drawing between the bases 

 of the stalks. The black arcuate line continues on the ante- 

 rior side of the eyestalks to the bases of the antennae. 



The thorax, neck and scutellum are black. Medially to the 

 point of attachment of the wings there is a seta bent back- 

 wards. The scutellum is relatively short. The scutellar spines 

 are well developed, about twice longer than the scutellum, 

 slightly longer than the thoracic setae, diverging backwards, 

 slightly bent medially. They are brown with black tips. The 

 setae on these spines are, unfortunately, brocken off in the 

 single specimen. 



The coxae are light gray-yellow. The femora are yellow- 

 brown, lighter at the basis, darker distally. The fore femora 

 are exceedingly swollen. The fore tibiae are black-brown, the 

 middle tibiae— yellow-brown, the hind tibiae are black-brown 

 with a wide light band in the middle. The tarsi are yellows- 

 brown, the first segment of the fore tarsi black-brown. 



The wings are translucent and have at the end of the 

 third longitudinal vein (R 4-1-5) a small, but distinctly hmited 

 brown spot. 



Abdomen wide, flat, at the base covered with whitish 

 hairs. The ground-colour of the abdomen is black, passing 

 into brownish towards the back. In some places the abdomen 

 has a bluish tint, especially on the lateral brown spots at the 

 posterior margin of the segments. 



The brown spots appear in the shape of 2 transverse 

 bands, medially very narrow; the first is near the groove of 

 the first long segment, the second — at the posterior margin 

 of the same segment. 



The low^er, ventral side of the abdomen is gray-yellow. 

 The dark colour of the upper side passes into it in the shape 

 of black triangles with the tase at the posterior margin of 

 each segment. 



One specimen, ?, from INIabira. ' 



Diasemopsis incerta n. sp. 

 Fig. 14 9 . 



Length 5 — 5^/^ mm. Width of head with eyestalks 4 — 6V4 mm. 



This species is very near to silvatica m. described above, 



and differs from it chiefly in the absence of a spot at the
