tins placed at the inner side of the femora ; the fourth tarsal joint 

 bilobed among nearly all. The abdomen composed of seven segments. 



Aclytia. 



Nov. gen. 



Body elongate, slender, sub-parallel, sub-depressed. Mentum longer 

 than broad, narrowed towards its base, impressed at the middle of the 

 apex. Labial palpi short, their terminal joint stout, subovate ; the 

 maxillary elongate, with a small subquadrate penultimate joint, the last 

 so shaped as to be intermediate between ovate and securiform. Mandi- 

 bles long, strongly arched, acute at apex, finely serrate on their inner 

 edge. Head nearly free, considerably narrowed behind, a good deal 

 narrowed and produced in front of the antennae.' Eyes large, prominent, 

 rounded, and finely facetted. Antenna elongate, but not so long as the 

 body, filiform, inserted on the forehead in front of the inner margin of 

 the eyes ; their basal joint almost pyriform, and about as long as the 

 third ; second shortest ; joints four to ten about equal, each a little 

 dilated towards the apex ; eleventh elongate -oval, of nearly the same 

 length as its predecessor. Prothorax transversal, widely rounded or 

 subtruncate in front, a little sinuous at the base, more or less rounded 

 laterally, margined, with a slightly convex disc. Scutellum oblong. 

 Elytra elongate, a little narrowed towards the front, rounded behind, 

 with distinct lateral rims. Legs elongate, tibia? straight, spinose at apex ; 

 tarsi shorter than tibiae, the anterior a little dilated, the two basal joints 

 about equal, obconical ; third shorter than second, of similar form ; the 

 fourth formed of two elongate lobes, between which the elongate fifth 

 joint is inserted ; claws thickened. Front coxa approximate, large, the 

 intermediate and hind part not much separated. Mesosternum with a 

 large frontal cavity for the reception of the anterior coxae in repose. 

 Metasternum moderate, slightly convex. Abdomen with six visible 

 segments, covered by the elytra. 



The type is A. fulvithorax. 



591. A. fulvithorax, n.s. Thorax yellow, the rest of the body 

 and the antennae black, the legs variable in colour, sometimes quite 

 black, sometimes fuscous variegated with testaceous, mandibles and 

 claws reddish. 



Head widest in line with the eyes, finely sculptured and pilose, 

 ciliated in front ; antennae and palpi pubescent. Prothorax much 

 broader than long, subtruncate in front, with obtuse angles, the base a 

 little emarginate in front of the scutellum and sinuated at side towards 

 the distinct hind angles, the sides are gradually curvedly narrowed in 

 front, with a sinuation near the posterior angle, its margin entire, much 

 thickened at the sides ; it is slightly raised in the middle, very finely 

 punctured, and, notwithstanding its pubescence, rather shining. Scutel- 

 lum almost triangular. Elytra of about the same width as the thorax, 

 elongate, sub-parallel, a little convex transversely, with rounded shoul- 

 ders, the lateral margins are a little explanate, becoming indistinct
