41 8 COLEOPTERA 



second, joints five to ten strongly pectinated, these joints decrease a 

 little in length but their lobes are about equal, and the eleventh is stout, 

 elongate-oval, and about as long as the lobe of the tenth. 



The head is large, being nearly three times the width of the front of 

 the thorax, ovate, resting on the apex of the thorax in repose : the parts 

 of the mouth are exposed, the lower side of the head being obliquely 

 truncated towards the front ; mentum indistinct ; labial palpi short but 

 quite perceptible, as long as the mandibles, the maxillary elongate, four- 

 jointed, the seconol and fourth joints about equal, the latter oviform, 

 thickened towards the extremity, it is longitudinally impressed at the 

 base : the upper part is rounded and somewhat convex behind, depressed 

 and flattened in front ; the epistome very transverse and distinctly 

 separated from the forehead ; labrum prominent, transversal, truncated 

 and ciliated in front ; mandibles robust, arched, with a tooth in line with 

 the front of the labrum ; eyes large, widely separated above, transversal, 

 widely and deeply emarginated in front, so as to be lunate, with their 

 greatest bulk below ; they are moderately facetted, and not convex. 



Prothorax longer than broad, conical, greatly narrowed anteriorly, 

 without perceptible front angles, the base is as wide as the elytra, with 

 prominent, acute, divergent angles overlapping the shoulders of the 

 elytra ; it is triangularly excised at the middle with a tooth-like protu- 

 berance at each side of the excision, and between these and the posterior 

 angles rather strongly sinuated. 



Scutellum large, elongate, cuneiform. 



Elytra elongate, attenuated posteriorly, with obliquely rounded 

 apices ; they do not cover the abdomen, and are separate behind, so as 

 to expose the ample wings. 



The legs are elongate and slender, the anterior shortest : the tibiae 

 are a little bent, and distinctly bispinose at apex ; front tarsi about as 

 long as tibiae, their basal joint stout, as long as fifth, the fourth smallest ; 

 the posterior are elongate, the first joint not so long as the other three, 

 third shorter than second ; claws pectinate : the apex of the tibiae and 

 tarsal joints is cavernose. each being inserted in the cavity of the 

 other. 



The coxa are large, the anterior subcylindrical, exserted, with their 

 cavities open behind and close to the hind margin of the prosternum ; 

 they are contiguous. The intermediate are slightly separated by an 

 elongate triangular mesosternal process, acute at apex, but extending 

 much beyond their middle; the hind pair are sub-contiguous. Meso- 

 sternum rather large ; metasternum large, convex, longitudinally furrowed 

 on the middle. Abdomen elongate, with six visible segments. 



I have named this genus in honour of Dr. Sharp, of Thornhill, 

 Dumfriesshire. The insect is more nearly related to Rhipistena than 

 any of the four groups of this family. 



735. S. hirtella, n.s. Elongate, slightly glossy ; head and thorax 

 blackish, elytra pitchy-red, reddest along the suture and margins, the 

 palpi, tarsi, and lobed joints of, the antennae black, the legs and basal 

 joints of the antennae obscure red, the claws and tibial spurs yellowish ; 

 the body is clothed with short, silvery-grey hairs, which are more sparingly 

 distributed on the thoracic disc than elsewhere.
