macrodactyliDjE. 135 



DESCRIPTION. 



Body piceous, thickly covered underneath, except the disk of the breast and abdomen, with 

 decumbent snowy hairs, minutely punctured, punctures most numerous in the upper side. Head 

 nearly black, covered with glittering decumbent hairs ; nose very obtuse and almost truncate, less 

 reflexed than in D. Backii, reflexed part obscurely rufous ; rhinarium, underside of the head, and 

 mouth with its organs, rufous ; antenna? reddish-yellow : prothorax nearly black with the sides a 

 little paler, with a longitudinal discoidal rather obsolete channel and an impression on each side ; 

 sprinkled with short glittering decumbent hairs : scutellum rufous, thickly covered at the base with 

 whitish decumbent hairs : elytra reddish-yellow tinted with green, sprinkled with short decumbent 

 whitish hairs, the lateral punctures are almost arranged in dense rows : abdomen rufous ; podex 

 thickly covered with snowy hairs : legs reddish-yellow ; tarsi darker ; posterior tibiae black, reddish 

 at the base ; posterior tarsi piceous. 



Variety B. Head and prothorax rufo-piceous ; legs rufous. 



C. Head and prothorax rufous mottled with dusky; elytra with a green spot at the 

 shoulders and tips ; posterior legs entirely rufous : trunk rufous. 



N.B. This may be distinct, but the prothorax has the channel and impressions observable in A. &c. 



Dr. Harris sent me a specimen of D. virescens as the Melolontha linearis of Herbst and 

 Schdnherr, but it is not likely that so accurate and minute a describer as Major Gyllenhal, who 

 usually lets no character escape him, should have overlooked the dorsal channel and lateral impres- 

 sions of the prothorax of this species. Besides the colour and other characters do not agree. 8

 and thickly punctured.

Taken by Dr. Bigsby in Canada. 



description. 



Very similar to Variety C of the preceding species ; but the body, with the exception of the 

 eyes which are black, is entirely of one colour, rufo-testaceous, the head, prothorax, and tarsi being 

 rather darker than the rest ; the eyes are larger and more prominent ; the head and prothorax, 

 especially the latter, are more thickly and minutely punctured ; and in this there is no dorsal chan- 

 nel ; its margins, especially the lateral, are more hairy, the elytra exhibit no humeral or apical green 

 spot ; and they are very slightly tinted with that colour.
