 BY a. R. WATBBHOUSE, F.Z.S., ETC. 



Grenus — ARTiCEBUa, Dalman. 

 Articeriis Duboulayi. Elongatus, rufo-testaceus, oculis nigris, supra 

 piibescens crebre piinctulatus ; caput porrectmn, elongatum, cylindricum, 

 ante oculos perparum angustius. Antennce compressce, longce, apice clavatce. 

 Thorax suhquadratiis, ante medium quadratum angustior, disco fovea 

 ohlonga impressus. Elytra striata suturali impressa. Abdomen supra 

 hasi concavum, postice convexum. Long. corp. 1 lin. 



The antennae in this insect are fully equal to the head and thorax 

 in length, and are terminated by a compressed truncated club. The 

 elongate and almost cylindrical head is furnished with a deep fovea on 



either side, in front of the eyes, into 

 which the antennae are inserted ; and 

 as this pit not only opens laterally but 

 forwards at the apex of the rostrum, 

 the antennae are much approximated at 

 the base, when they are directed for- 

 wards. They are curved inwards at 

 the apex. Viewing the insect from 

 above, they appear slender and to be 

 suddenly dilated into a triangular club 

 at the apex ; but, viewed from the side, 

 the antennae, owing to their vertically 

 compressed form, present a very dif- 

 ferent aspect ; they then appear rather 

 stout, and the width gradually increases 

 to the apex ; the club no longer pre- 

 senting a suddenly dilated form. The organs under consideration ap- 

 pear to be composed of an elongated scape, which is smooth and only 

 pubescent at the apex ; a funiculus composed of several joints 

 anchylosed, and distinguished by being somewhat punctured and rugu- 

 lose and densely pubescent, and finally by a club or larger truncated 

 terminal joint, which is smooth and less densely pubescent. The eyes 

 are rather small, and made up of comparatively large facets. The head, 

 thorax, and elytra are almost destitute of gloss, being densely and finely 

 punctured and pubescent ; the abdomen is glossy and spariugl}'- punc- 

 tured. On the vertex of the head are two small dark raised spots, 

 having much the appearance of ocelli.* The thorax has the disc de- 



Articerus Duboulayi. 



' Similar raised spots are lepresenffd by Mr. Wpstwood in his figure of ArHcerus brazilientis.
