 be more brownish than black, and in the ? the abdomeit

Dasyornma dissiniilis, sp. nov. 

 (PI. XXVII., figs. 5, 6.) 



Very similar to D. inaculipennis, but easily distin- 

 guished by the apparently bare eyes, which, however, ai'« 

 found to be scantily pubescent when seen under a low- 

 power microscope; the wings without spots, suffused witk 

 brown. 



S . Thorax and abdomen shining black, head covered 

 with brownish grey tomentum, the first two' joints of the 

 antennse reddish, palpi brownish black with black hairs.; 

 proboscis and third joint of antennjs black ; hairs on 

 thorax, scutellum and abdomen black; feanora shining 

 black or brown, tibias and tarsi brownish with black apices,, 

 the legs are, . however, variable in colour. 



Length, 6 mm. 



$ var. This variety, which may possibly X'epresent 

 a distinct species, has the abdomen brown, with apices of 

 segments black ; the legs much darker, and the antennse 

 entirely black ; the general appearance of the insect is; 

 distinct, but there seem to be no characters other than 

 colour and size between it and the typical form. 



Length, 5 mm. 



$ . Evidently belongs to the above variety, and is 

 similar in colouration to the: brownish form of D. maciiU- 

 pennis. The frontal and ocellar spots are united, the 

 thorax stripes are obscured with blackish, and nearly all 

 hairs black. It also differs by having only scanty pube- 

 scence on the eyes. 



Brown ; ocelli, frontal tubercle, third joint of an- 

 tennae, three obscure stripes on thorax, apices of joints 

 of legs, apical borders of abdominal segments, hair of
