520 COLEOPTERA. 



Head neti ]y as large as thorax, slightly narrowed anteriorly, curvedly 

 narrowed behind the large prominent eyes, bifoveate between them, 

 flattened or broadly impressed between the widely separated, slightly raised 

 antennal tubercles, with a fovea-like impression just behind each of the 

 latter. Thorax cordiform, of about equal length and breadth, rounded and 

 widest before the middle ; trifoveate near the base, the transversal connect- 

 ing stria obsolete. Elytra subquadrate, much broader than thorax, some- 

 what narrowed before the middle, indistinctly ])unctate ; sutural striae 

 distinct, sUghtly punctiform at the base, where there is a small ])uncture 

 alongside each ; intrahumeral impressions short, moderately broad and deep. 

 Hind-body as broad as elytra, shorter ; basal segment horizontal, half the 

 length of the elytra, and as long as the other deflexed segments combined. 

 Legs moderately elongate, simple. 



Antennae about as long as head and thorax, rather slender, finely 

 pubescent ; basal joint but little longer than the oblong second ; joints 3-5 

 more slender than the second but almost as long, sixth and seventh shorter 

 but ratlier larger than the small eighth : ninth larger, yet smaller than the 

 subquadrate tenth, terminal subcorneal, largest. 



Smaller than A. euplectoides (1869), the thorax less dilated before the 

 middle, with smaller basal foveae, the antennae shorter, the legs more slender, 

 and the coloration uniformly paler.

 4041. Inocatops impressus sp. nov. 



Nitid, oblong-oval, moderately convex, depressed across the middle, 

 impunctate ; rufous, antennae and legs rufo-testaceous, tarsi flavescent ; 

 covered with elongate, suberect, fulvous pubescence ; antennae and tibiae 

 finely setose. 



Head moderately elongate, about a fourth of the width of thorax. Eyes 

 minute. Thorax a third broader than long, curvedly narrowed before the 

 middle, with depressed and indistinct front angles ; base depressed and 

 bisinuate near the middle, truncate towards the rectangular angles ; lateral 

 margins fine and somewhat indistinct ; at the middle of the base there is a 

 large but not deey) iin])rossion. Elytra oblong-oval, double tlie length of 

 thorax, of about the same width as it is at the base, the shoulders angular 

 but on a lower level ; the broad scutellar depression extends along the suture 

 but becomes much narrower towards the middle. 



Front and middle tibiae straight inwardly, the latter pair slightly 

 expanded and oblique at the extremity ; the j)osterior slender at the base, 

 gently curved along the inside, quite oblique at the outer extremity, tarsi 

 rather longer than the others. 



Antennae stout, rather longer than the head and thorax, second joint 

 fully as long as the basal ; third oblong, shorter than preceding one but 

 longer than fourth, the fifth and seventh larger than sixth or eighth, ninth 

 and tenth much broader, the terminal rather longer at one side than the 

 other.
