ATTELABUS. ll 
24, Attelabus quadratus, sp. n. 
?. Rufo-sanguineus, nudus, nitidus; prothorace conico, transversim bi-impresso: elytris brevibus, latis, 
lateribus pone humeros elevatis et lateraliter compressis. 
Long. 5 millim. 
Hab. Nicaracua, Chontales (Janson). 
Head elongate, the summit of the vertex canaliculate; eyes convex, widely sepa- 
rated, the space between them bisulcate, the interval between the sulci broad, uneven. 
Thorax almost impunctate, transversely impressed towards the front, and also with an 
angulate transverse impression extending completely across it. Scutellum extremely 
broad. FElytra with an obtuse elevation on each side behind the shoulder; near the 
base and towards the suture with deep strie, which are continued backwards as series of 
extremely fine punctures; behind the scutellum there is a slight depression. 
Two females. 
Allied by the form of the elytra to A. callosus ; but, besides differing much in size and 
colour, the head is differently formed, the eyes in A. quadratus being prominent and 
the grooves between them separated by a broad interval. 
II. Anterior femora irregularly serrate ; form extremely short and broad.

Jekel considered a specimen from Mexico sent to him by Sallé as distinct; but 1 am 
not able to find any satisfactory characters to distinguish individuals of our region from 
examples found at Monte Video, these localities being apparently the extreme points of 
its distribution ; the characters relied on by Jekel are but slight, and some of them are 
not confirmed by the examples before me. 
A, ater appears rare in our region, only five examples having come under my obser- 
vation. We figure the example found in Guatemala by Mr. Champion.
