Tomocephalus abdominalis, Cand. Ann. Soc. Ent. Belg. 1889, p. 118 (Elat. Nouv. iv. p. 52) \ 



Hab. Mexico, San Andres Tuxtla (Salle) ; Guatemala, Senahu and Sinanja in Vera 

 Paz (Champion); Panama, Volcau de Chiriqui (Champion), Chiriqui 1 . 



I have seen ten specimens of this species, including the type, kindly sent by 

 Dr. Candeze for examination. In all of them the abdomen is sanguineous or rufous, 

 except at the apex. 



4. Tomocephalus sardioderus. (Tab. XXII. fig. 3, $ .)

 Tomocephalus sardioderus, Cand. Cat. Method. Elat. p. 188 2 . 



Hab. Mexico 2 , Cordova (Salle 1 ). 



The description of this insect is not clear, as it appears to have been made from more 

 than one species. Of the four Mexican specimens representing it in the Salle collection, 

 apparently all females, one is certainly referable to T. substriatus, one to T. abdominalis 

 (agreeing with the type of that species), one, the only example I have seen, to 

 T. sardioderus, and one to the insect here described under the name T. melanotus. 

 The example (?) of T. sardioderus does not, however, differ from the S.-American 

 T. sanguinicollis, Latr., in having the thorax more elongate as stated 1 , this remark 

 applying to T. abdominalis and T. melanotus only ; it is closely allied to T. abdominalis, 

 of which it may be a colour-variety, but differs from it in having the elytra a little 

 more closely punctured. From T. substriatus (?) it may be separated by the more 

 convex and less coarsely punctured thorax, the sides of which are more rounded, the 

 less flattened apex of the elytra, and the rufous prosternum. 



5. Tomocephalus hicolor. (Tab. XXII. fig. 4, e .) 



Elongate, narrow, rather convex, very shining ; deep black, the elytra with the basal half or three-fifths, 

 except along the suture, flavous or stramineous, the tarsal claws rufous ; above rather sparsely clothed 

 with long hairs, which are erect on the head and prothorax and semierect on the elytra, and partake of 

 the ground-colour, the under surface sparsely clothed with decumbent fulvo-cinereous hairs. Head 

 sparsely, rather finely punctate ; antennae in the male nearly half the length of the body, shorter in the 

 female, the joints from the fourth broadly widened and serrate. Prothorax almost as long as broad in 

 the male, shorter in tbe female, strongly narrowed in front, the sides rounded at the middle and sinuate 

 behind ; the hind angles moderately long and divergent, slightly incurved at the tip, carinate ; the surface 

 with widely scattered fine punctures. Elytra about three and one-fourth times the length of the 

 prothorax, a little flattened on the disc, rounded at the apex, the sutural angles rather sharp, the base 

 depressed near the shoulders ; with widely scattered, irregularly arranged, very fine punctures, and, on 

 the flavous portions, with regular rows of coarse punctures showing through from beneath the surface. 

 Beneath very sparsely, finely punctate. 



Length 8|-11, breadth 2|-3 millim. ( d $ •)
