ETTPHENGES. 27 



narrower ; the first joint elongate, attenuated, subdilated, and trun- 

 cate at the apex ; the second shorter, and of the same form ; the 

 third subovate, not bilobed ; the whole densely fringed with close 

 pubescence; the last joint terminates in a bladder-like inflation, 

 which, from above, completely conceals the terminal claw, and which 

 (more distinctly seen when viewed obliquely) itself is terminated in 

 a pseudo-claw, similar in form and size to the claw which it protects.

Long. corp. 3 lin., lat. 1-| lin. 



Oblong-ovate, broad, robust, impubescent, of a palish brown-red 

 cv-our throughout. Head transverse, narrow, elongated in front : be- 

 tween the upper part of the labrum and the base of the antennae is 

 a triangular carination, which is bisected by a longitudinal medial 

 carination from the base of the antennae : above the base of the an- 

 tennae and between the eyes is a Y-shaped ridge, extending in an 

 oblique direction towards the inner and upper margin of the eyes ; 

 this ridge is most apparent when seen obliquely : eyes tolerably 

 large, situated at a short distance from the base of the head, and 

 not extending laterally as far as the angles of the thorax : the surface 

 very obsoletely clothed (when viewed under a very high magnifying 

 power) with flavous pubescence, especially near the inner margin of 

 the eyes ; the colour below the base of the antennae flavo-rufous ; 

 above, of a darker brown rufous. Thorax quadrate, rectangular, 

 rectilinear, slightly broader than the head, considerably narrower 

 than the elytra ; the anterior and posterior angles subacute ; the an- 

 terior angles subdepressed, the sides marginate, while at the base is 

 a broad and very shallow transverse depression ; the surface is im- 

 punctate, glabrous, and thickly clothed at the sides with a close 

 tawny pubescence. Scutellum triangular, fuscous, indistinctly clothed 

 with flavous pubescence. Elytra much broader than the thorax, 

 slightly attenuated towards the apex; punctures, arranged in the 

 form of striae, become almost entirely obsolete near the apex : a little
