THE CANADIAN ENTOMOLOGIST. 15 



This species has been distributed with the manuscript name 5?/^- 

 angulaia Jac. I have received 4 co types from Messrs. Staudinger & 

 Bang-Haas. 



D. ificonspicua, nov. sp. (Jac. in litt.). 



Entirely palHd testaceous, with black eyesj antennae fuscous in the 

 middle, mandibles dark. Head with a deep frontal fovea, antennae nearly 

 three- fourths as long as body, 3rd joint nearly as long as 4. Thorax nearly as 

 broad as long, strongly obliquely bifoveate and somewhat depressed 

 behind ; elytra slightly dilated to the rear, a faint piceous spot on the 

 shoulder, and with punctures thick, moderate and obsoletely arranged in 

 rows. Length, 6 mm. 



Two examples, Callanga, Peru. 



This species has been distributed with the manuscript name iîicon- 

 spictia Jac. My two examples were sent me as co-types by Messrs. 

 Staudinger & Bang-Haas. The species is analogous to many in the latter 

 part of sec. i. The elytra are not plicate. 



D. guyanensis, nov. sp. 



Head shining black ; mouth parts flavous ; antennae piceous at base, 

 fuscous in middle, last four joints flavous, extreme tip of 11 dark. Thorax 

 rufous, shining, lightly bifoveate, depressed ; scutel black ; elytra strongly 

 plicate, flavous, with a short common suturai and a long humeral stripe 

 black : punctation thick and subrugose. Body below flavous, breast black, 

 legs flavous. 



Var. with shoit submedian, subsutural black stripe or spot. 

 Three examples, Br. Guiana type form, i var. do., and i Pachitea, 

 Peru. Length, 6-6^ mm. 



The antennae are long and slim, reaching nearly three-fourths the 

 length of the body ; the thorax is very slightly sinuate behind, rounded in 

 front, almost square, and noticeably polished j the suturai stripe is of 

 medium width, a little less than one--third the length of the elytra, hardly 

 narrowed behind; the humeral stripe stops just round the bend of the 

 convexity, and is evidently sometimes interrupted at a little behind the 

 middle. Both stripes attain the base. This species resembles the forms 

 in sec. r, division O. 



D. beriottii, nov. s p. 



Head rufous ; labrum and spots on the vertex piceous ; antennce 

 black, joints 8-9 flavous with bases and tips daik. Thorax rufous, rather
