concave. This sex is more densely clothed with scales than the 

 other ; the males, indeed, are often almost destitute of scales. 



Apocyrtus prof anus. 



Ap. profanus, EricJis. 1. c. p. 379 ; Schonh, v. pt. 2. p. 852. 



Spluerogaster profanus, Esch.sch. 



Oblongus, fuscus, parum nitidus, thoracis pectorisque lateribus parce viridi- 

 squamosis ; fronte canaliculata, thorace granulis nitidis crebre adsperso; 

 elytris subovatis, subconvexis, thorace parum latioribus, crebre granu- 

 latis, margine basali dense viridi-squamosis, femoribus ferrugineis. 



Var. /3. Elytris tibiisque etiam ferrugineis. 



The above description, which is from Schoenherr, very well cha- 

 racterizes an insect brought home in tolerable abundance by Mr. 

 Cuming. I have before me specimens exhibiting three distinct va- 

 rieties : the first is black, and well- clothed with green scales ; the 

 second is pitchy, has the femora reddish at the base, and is less densely 

 clothed with scales, and the third is of a pitchy red colour, almost 

 destitute of scales ; these being chiefly confined to a narrow band 

 across the base of the elytra. I may add, of the first variety there 

 are both sexes, of the second variety there are but females, and of 

 the red variety* there are no females. 



This species greatly resembles the Ap. impius, but is usually rather 

 smaller, and the elytra differ in having minute glossy tubercles. 



The rostrum is rugose above, has a broad and shallow longitudi- 

 nal impression in the middle, and another on each side of this, which 

 is broad at its commencement, near the transverse line at the base 

 of the rostrum, and becomes gradually narrower to its point of ter- 

 mination, which is in a line with the point of insertion of the an- 

 tennae : on the side of the rostrum is a deep longitudinal groove 

 which runs into the groove for the antennas. The thorax is globose 

 and covered with minute glossy tubercles : in the male it is very 

 nearly equal in width with the elytra ; in the female the sides are 

 less boldly rounded, and it is decidedly narrower than the elytra — 

 these are covered with rugse and minute tubercles. In the male the 

 elytra are rounded at the extremity, and the terminal segment of 

 the abdomen is semicircular and rugose. In the female the elytra 

 are ovate, and attenuated and pointed behind ; they have a subapical 

 prominence on the suture. The terminal segment of the abdomen 

 is conical, glossy, and has a large shallow fovea. Length from 3J 

 to 5 lines. 



Apocyrtus Chevrolatii. 



Ap. niger, femoribus rubris, antennis, tibiis, genibusque piccis : capite inter 

 oculos punctato et linea longitudinali impressa ; rostro rugoso, basi ca- 

 naliculate ; thorace subgloboso, tuberculis crebris obsito, dense viridi- 

 squamoso, linea transversa in mediam denudata ; elytris convexis, ovatis, 

 rugosis et tuberculis minutis obsitis, squamis viridibus ornatis, fasciis 

 duabus, et plaga utrinque subapicali, denudatis. Long. corp. 4 — 5 lin. 



This species is about equal in size to the Ap. profanus, which it 

 very nearly resembles also in form ; it is readily distinguished by the 



* Tbe difference of colour certainly does not arise from immaturity.
