2U [April, 



were sent to Dr. J. Sahlberg for identification, who returned them 

 ■with the name D. assimilis; but, on examination of the genitalia, I find 

 they agree exactly with Fieber's figures of the insect now described. 

 Under these circumstances, I have referred D. assimilis, Sahib., to 

 D. Minki, Fieb. 



Pale yellowish or brownish-yellow. Elytra : anterior margin very 

 pale yellowish- white. 



Head — crown yellow ; length down the centre about equal to the width across the 

 anterior margin of the ejes ; anterior sides slightly convex ; apex with a very 

 short, nearly straight black streak on each side, and sometimes another along the 

 margin ; occasionally both ai'c obsolete. Face more or less dark brown, with a 

 more or less distinct narrow pale longitudinal line, and on each side about seven 

 transverse whitish lines, sloping off in a line with the upper margin of the lorse, 

 inner extremities of two or three on the fi'ons somewhat knotted or comma- 

 shaped ; intervening brown spaces broadest. Cheeks and lorcB yellowish, or the 

 former brown, with the exterior and lower margin yellow, and the latter nar- 

 rowly margined with brown. 



Thorax — pronotum and scutellum yellow. 'Elytra pale yellowish or greenish-yellow, 

 semi-transparent, $ longer, $ as long as the abdomen; nerves fine, almost 

 white ; anterior margin very pale yellowish-white, broadest at the base ; apical 

 and apices of the adjoining ante-apical areas faintly brownish, sometimes 

 with very narrow somewhat darker margins. Legs yellow. Thighs : 1st and 

 2nd pairs with or without the usual bands ; 3rd with a black line along the upper 

 margin at the apex ; upper and under-side with a broad black longitudinal 

 streak, not reaching the base or apex. Tibia : 3rd pair yellow, with a more or 

 less broad black line inside next the inner mai'gin ; outer margin with black 

 punctures, in which the pale spines are set. Tarsi yellow, or with a fuscous 

 shade. Length, 1^ — IJ line. 



9. PASCUELLUS, Fall. 



In the form of the genitalia, very like D. MinJci, the most per- 

 ceptible difference being simply a deeper sinuation on the sides of the 

 posterior margin of the last abdominal segment of the $ of that 

 species. Another difference is in the total or almost total absence of 

 the pale yellowish-white anterior marginxof the elytra of the last 

 named. As the extremes of variation constantly occur in this genus, 

 it is possible that these two species are not really distinct. 



Pale yellowish-white. Elytra pale, almost transparent ; apex of 

 the ante-apical area adjoining the inner apical one with a dark brown 

 spot. 



Head — croivn pale yellowish-white, with a narrow black line in front on each side of 

 the centre, sometimes interrupted or obsolete. Face brown, with a whitish 

 central line, and about six transverse white lines on each side. Cheeks and lora 

 . yellowish. ^
