94 Mr. D. Sharp's Contributions to the 



the 11th joint large, stouter than tlie 10th, and about 

 twice as long. Head broad and short, black and shining, 

 extremely finely, almost imperceptibly, punctured. Thorax 

 pitchy, paler at the sides, naiTowed towards the front, the 

 base slightly sinuate on each side, the hind angles rounded 

 and ])rojecting a little backwards ; it is very finely and 

 indistinctly ])uuctured. Scutellum large, smooth and im- 

 punctate. Elytra fully a third longer than the thorax, 

 straight at the sides, the outer angle not much rounded ; 

 they have a deep, narrow channel close to the external 

 margin, extending from just below the humeral angle to 

 the extremity ; they are finely punctured, but more dis- 

 tinctly so than the thorax. Hind body rather closely and 

 distinctly ]iunctured; segments 2 — 5 distinctly margined, 

 6th and 7th immarginate. Legs yellowish, short; meso- 

 thoracic carina but little prominent. 



In the female the dorsal plate of the 7th segment ends 

 in four stout but long acuminate spines ; these project 

 about equally far back ; the notches between them are 

 only narrow, but are elongate ; the lateral ones reach a 

 little farther fonvards than the middle one ; the ventral 

 plate ends in four shorter and more Avidely-separated 

 spines; of the notches between these the middle one is 

 not deep, but the lateral notches extend considerably 

 farther forw'ards than the middle one.

CONURUS. 



The Tdchj/porini bearing this name are very easily 

 recognized from the fine, delicate pubescence Avith Avhich 

 all the parts of the body are clothed. Species of the 

 genus are proliably to be found in nearly all countries, 

 and, though only five species have yet been described 

 from South America, there is but little doubt that these 

 insects will be found to be numerous there, for I have 

 nine species from the neighbourhood of liio de Janeiro 

 alone in my collection. 



1. Conurus latus, n. sp. Ferrugineus, convexus, pube- 

 scens, antcnnis articulis 5 — 10 nigris, ultimo pallido basi 

 nigro. Long. corp. 2^ lin. 



A broad species, very convex about the thoi-ax and 

 elytra, with the exception of the atitenn;r of an uniform 

 tawny colour. The antennic moderately long, thickened
