Genera and Species of Colooptera. 367 



wath 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. 



DcEsus [CerambycidaDJ. 



Head rounded, slightly contracted behind the eyes. Antennpe 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 sub triangular. Prothorax nearly 

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

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

 angle produced. Legs moderate, tibife slightly cm-ved 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 be a 

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

 to a Telepliorus, but is related to Vesjaerus, 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 be noted that whilst in 

 Vespenis the tibiae are slender and perfectly straight, in Doesus they 

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

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

 case in Ves^erus. The form and position of the coxae, palpi, and 

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

 are so far identical as to call for no further notice. 



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



Z). testaceo-ferrugineus, subnitidus ; elytris breviter pilosis ; ocidis nigris. 



Hab. India. 



Testaceous inclining to fen'uginous ; head, prothorax, femora, except 

 beneath, and basal joint of the antennas 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^ lines.
