FAMILIES TROGOSITIDAE AND CUCUJIDAE 115 



Melambia sp. prox. memnonia, Pascoe. 



REFERENCE. Pascoe, Journ. of Ent. i, p. 320, 1862. 



Habitat. Changa Manga Plantation, Punjab. 



Habits. Predaceous upon the wood-borers Sinoxylon crassum and 

 S. anale (vide p. 166). 



TENEBROIDES. 

 Tenebroides (Trogositita) rhizophragoides, Walker. 



REFERENCE. Walker, Ann. Nat. Hist. 3rd ser. iii, p. 53 (1859). 



Habitat. Seoni, Central Provinces. 



Habits. -Feeds predaceously on Sinoxylon crassum in Terminalia tomen- 

 tosa in the Central Provinces (vide p. 166). 



TlMNOCHILA. 



Timnochila coerulea, Olivier, var. 

 REFERENCE. Oliv. Ent. ii, 19, p. 6, pi. i, fig. i. 



Habitat. North-West Himalaya. 



Habits. This elongate blue-black large trogo- 

 sitid is predaceous upon the bark-borers Tomicus 

 longifolia and Polygraphus longifolia in the chir pine 

 (Finns longifolia}. I first took specimens of it at 

 Jermola in Jaunsar in the Western Himalaya. It 

 may also attack the cryptorhynchid weevil of this 

 pine, but that I have not personally observed. The FIG. 79.- 

 insect is a most useful one in the forest (vide p. 561). r/W^Hhi 



Family CUCUJIDAE. 



The forest members of this family vary considerably in appearance. 



Some have the small flattened, rounded, or squarish 



Beetle. forms and brown or yellow colour which is commonest 



in the family. Others, however, differ entirely In mi 



this type, having elongate black shining forms with heavily jointed and 

 knobbed antennae (e.g. Hectarthruni}. The tarsus in the family is apparently 

 four-jointed, and the antennae are long, often with a clubbed top to them. 



The larva is an elongate grub with jointed antennae on a large head, 

 three pairs of jointed legs on the thoracic segments, \vhieh are not much 

 wider than the abdominal segments, the last three or four <>f \\hieh may 

 taper posteriorly, the last being small, or the abdominal segments ma\ 

 increase in size and width posteriorly, the last hem- lar-e and terminating 

 in small processes. 



Some of the members are, as mentioned already, easy to distinguish: 

 but the majority perhaps are by no means easy to rccogni
