Da^yomma distiiinilis, sp. nov. 

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



Very similar to D. macuUpennis, but easily distin- 

 guished by the apparently bare eyes, which, however, are 

 found to be scantily pubescent, when seen under a low 

 power microscope; the wings without spots, suffused with 

 brown. 



$ . Thorax and abdomen shining black, head covered 

 with brownish grey tomentum, the first twoi joints of the 

 antennje reddish, palpi brownish black with black hairs; 

 p!-oboscis and thii'd joint of antennas black ; hairs on 

 thorax, scutellum and abdomen black ; femora shining 

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

 the legs are, however, variable in colour. 



Length, 6 mm. 



$ var. This vaiiety, which may possibly represent 

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

 segmentg black ; the legsi much darker, and the antennae 

 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. niaculi- 

 jjennis. 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 pubc- 

 sconco on the eyes. 



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

 tennae, three obscure stripes on thorax, apices of joint."^ 

 of legs, apical borders of abdominal segments, hair of
