MYCTEEISTES. 39 



(5 . The head is excavated above and bears a short horizontal 

 himina behind, which is slightly notched in front. The angles of 

 the clypeus are acuminate and the front margin is produced in the 

 middle into a small horn curving upwards and dilated in front. 

 The club of the antenna is rather long, the front tibiae and all the 

 tarsi are longer than those of the female, and the abdomen is longi- 

 tudinally channelled beneath. 



$ . The clypeus is simple but the anterior angles are produced 

 into short, blunt processes. 



This species is extremely like M. microplvjllus, but it is a little 

 shorter and the prothorax is less finely and evenly sculptured, 

 distinctly punctured near the middle and broader at the base. 



Length 17-18 mm.; breadth 8 mm.

o. Mycteristes (Cephalocosmus) aiiritus, sp. n. 



Coppery, with the head, prothorax, legs and lower surface tinged 

 with red and the elytra with green, the whole body very sparsely 

 clothed with minute yellowish setae, which are longer vapon the 

 head, sternum and sides of the abdomen. It is opaque above, 

 depressed, broad at the shoulders and not very long. 



(S . The head is coarsely rugose, concave, with the clypeal 

 margin rounded and produced in the middle into a short horn 

 strongly recurved and bifid at the end. The lateral margins of 

 the head just above tlie antennal sockets are produced upwards 

 and forwards forming a pair of hooked laminae in front of the eyes. 

 The pronotum is rugosely punctured, almost flat, and forms a 

 nearly regular heptagon. The scutellum and elytra have a silky 

 lustre, and the former is acute, not very long, and bears a few 

 setigerous punctures. The elytra are gently sinuated behind the 

 shoulders and taper from there to the end, and each has a strong 

 median costa which is bent towards the shoulder. They are 

 moderately punctured in the anterior part, the punctures changing 

 gradually to longitudinal striolae. The apical angles are a little 

 produced. The pygidium is finely transversely rugose and the 

 metasternimi and abdomen coarsely rugose, but nearly smooth along 

 the middle. The sternal process reaches a very little beyond the 

 middle coxae. The legs are slender and the front tibice slightly 

 cui'ved, furnished with three very inconspicuous teeth at the outer 

 edge and a dense brush of yellow hairs at the inner edge. The 

 tarsi are a little longer than the tibiae. 



The 2 is unknown. 



Length 17 mm. ; breadth 9 mm.
