(>36 Description of the Male 



Goliathvs torquatus. 



Form. — Head quadrate, having on each side, in front of 

 the eyes, a short pointed process, the apex of which is slight- 

 ly recurved : clypeus produced anteriorly into a long, pointed, 

 and slightly recurved process. On the upper surface of this 

 process, and about midway between the base and apex, are 

 two small triangular projections, which are separated by a 

 longitudinal groove. Eyes somewhat prominent. Thorax 

 slightly convex, broader than long, — the length being about 

 equal to two-thirds of the width ; truncated anteriorly ; the 

 posterior margin slightly produced in the middle, but emar- 

 ginate opposite the scutellum. At the basal half of the tho- 

 rax the lateral margins are nearly parallel, but beyond this 

 they converge towards the head. The thorax is widest at the 

 base and most contracted in front, where it is in fact no wider 

 than the head : the posterior angles are rounded. Scutellwn 

 large, nearly triangular, rather longer than broad, with the 

 anterior margin somewhat rounded. Elytra depressed, con- 

 vex near the apex externally, but near the suture there is a 

 concavity ; longer than broad, — the width being about four- 

 fifths of the length : they are broadest at the base and nar- 

 rowest at the apex : their lateral margins approach nearly to 

 a straight line, but are slightly dilated in the middle, indis- 

 tinctly contracted near the shoulder, and dilated again and 

 rounded at the shoulder, or external anterior angle : at the 

 apex they are rounded, but near the suture there is a small 

 notch in each elytron, leaving an acute angle. The sternum 

 is produced anteriorly into a broad flat process, the lateral 

 margins of which are parallel, and the apex is obtusely point- 

 ed, and fits in between the coxae of the anterior pair of legs. 

 The upper plate of the terminal segment of the abdomen is 

 slightly convex, vertical in position, of a triangular form, 

 broader than long, and rounded at the apex. Femora sim- 

 ple. Anterior tibia dilated at the apex, externally into a 

 large, flattened, and pointed tooth, the apex of which is 

 slightly recurved ; and internally into a broad, forked pro- 

 cess : besides the external apical teeth there are two others, 

 the larger one about midway between the base and apex 

 of the tibia, and the other between this and the base ; and 

 between these external pointed processes the tibia is deep- 

 ly emarginated. On the inner side of the tibia, indepen- 

 dantly of the forked process mentioned, there are four denta- 

 tions, of which the two intermediate are the largest. The 

 tibia of the middle and posterior pairs of legs have a sharp
