CALLINOMES. 215 



Genus CALLINOMES. 



Callinomes, Westw., Thes. Ent. Oxov., 1874, p. 26 ; Heller, Notes 

 Leycl. Mus. xix, 1897, p. 177. 



Type, Callinomes voUenJiovii, Westw. (Java). 



Mange. The Oriental Region. 



Very elongate, with the prothorax subcircular. Head strongly 

 convex, with the eyes small and the organs of the mouth completely 

 shut in by the mentum. Basal joint of the antenna very large, 

 forming a plate exactly fitting the space between the mentum, 

 front coxa and episternum, and enclosing the remainder of the 

 antenna when at rest. Mentum very large, flat and smooth, 

 occupying the whole lower surface of the head and projecting 

 backwards between the coxae. Mesosternum very narrow and 

 not prominent between the middle coxse. Legs moderately long, 

 the front tibia armed externally with two minute and rather distant 

 teeth. Tarsi 4-jointed, very short and compact, with minute 

 claws. Terminal spiracles elevated. 



J . The abdomen is a little excavated beneath and the front 

 tibia bears a long apical process beneath. 



This genus shows all the peculiar features of the Ceemasto- 

 CHiLiNA at their greatest development. The remarkable box- like 

 structure formed by the enlarged mentum and basal joint of the 

 antenna, which completely shut in the delicate head-appendages, 

 the thickening of the tarsi and reduced number of their joints, are 

 parts of a protective adaptation similar to that found in beetles 

 of many different families which inhabit the nests of Ants or 

 Termites.

(n. syn.). 



Black, with the upper surface of the head and prothorax and 

 the basal quarter of the elytra (except the humeral callus) brick- 

 red, a narrow stripe of the same colour extending backwards to 

 beyond the middle near the outer margin of each elytron. The 

 upper surface is opaque and the lower surface, with the pygidium 

 and legs, shining black. 



It is a large elongate species, rather fiat above. The Jiead and 

 pronotum are rather finely punctured, the sides of the clypeus 

 nearly vertical, and the front margin nearly straight and scarcely 

 reflexed. The protlwrax is almost circular, a little broader than
