Genera and Species of Coleoptera. 307 



with many others in the Longicorn families, yet taken in connexion 

 with the fact that one has a type of coloration different from the 

 other, will, I think, justify its adoption. 



Dcestjs [Cerambycidas]. 



Head rounded, slightly contracted behind the eyes. Antennae setaceous, 

 distant at the base, longer than the body, the first joint short tumid, 

 the second very short, the remainder subequal. Eyes very large, ob- 

 long, nearly entire. Lip very small, rounded anteriorly. Palpi grow- 

 ing gradually thicker, the last joint subtriangular. Prothorax nearly 

 equal in length and breadth, narrower in front, rounded behind, the 

 sides carinated. Elytra wider than the prothorax, parallel, the humeral 

 angle produced. Legs moderate, tibiae slightly curved externally, their 

 margins tuberculate and fringed with short hairs, the first tarsal joint 

 shorter than the two next together. Abdomen soft. 



The above description is drawn up from what appears to he a 

 male, in the collection of Major Parry. It has a striking resemblance 

 to a Telephones, but is related to Vesperus, although the form of the 

 head and prothorax is so far different that we miss the slenderness 

 which gives such a remarkable contour to the species of that genus; 

 the presence also of a well-marked carina along the side of the pro- 

 thorax, which, however, does not extend its whole length, would 

 alone suffice to distinguish it. It may also he noted that whilst in 

 Vesperus the tibiae are slender and perfectly straight, in Dcesus they 

 are tolerably robust and curved externally, and the basal joint of 

 the tarsi is shorter than the two next together, which is not the 

 jase in Vesperus. The form and position of the coxae, palpi, and 

 antennae, except* that the latter are more distant at their insertion, 

 T re so far identical as to call for no further notice. 



Dcesus telephoroides. (PI. XVII. fig. 4.) 



D. testaceo-ferrugineus, subnitidus ; elytris breviter pilosis ; oculis nigris. 



Hub. India. 



Testaceous inclining to ferruginous ; head, prothorax, femora, except 

 beneath, and basal joint of the antennae smooth, somewhat shining; 

 elytra covered with very short greyish hairs, and each with three 

 slightly raised lines ; body beneath paler, with a very sparse pubes- 

 cence ; eyes black ; tips of the mandibles dark brown ; head slightly 

 broader than the prothorax, rather convex in front ; eyes prominent ; 

 prothorax but slightly convex; elytra considerably wider than the 

 prothorax, rather elongate. Length 7 A lines.
