FAMILY BOSTRYCHIDAE 



iG- 



X 3 



I took specimens of this Teretnus in the tunnels of S. crassum and 

 S. analc in sissu-trees at the Changa Manga Plantation in May 1905. The 

 histerids were in company with T. intnisinn and T. Stebbingi, and are 

 predaceous upon the Sinoxylon beetles. 



Other beetle predators upon 5. crassum and 5. anale are species of the 

 genus Bothridcres (family Colydiidae), the genera Alindria, Melambia, and 

 Tcnebroidcs (family Trogositidae), and Hcctarthrum (family Cucujidae). 



Bothrideres andrewesUp. 112).— The beetle is narrow, elongate, parallel, shining, 

 and li-lit brown in colour above and below. The head is rather large, and protrudes 

 beyond the prothorax ; eves round and fairly prominent ; antennae end in a terminal club. 

 Prothorax a little separated from elytra, squarish; head and 

 prothorax strongly punctate above. Elytra deeply ridged longitu- 

 dinally, and punctate between the striae. Legs light brown ; tarsi 

 four-jointed, none of joints being broad ; hind coxae are separated, 

 fore and middle ones close to one another ; tive visible ventral 

 segments. Slender, active insects ; very quick in their move- 

 ments. 



Life History.— i:\\\s beetle, which is predaceous, 

 has been taken in sissu wood at Changa Manga, in 

 the galleries of S. crassum and 5. anale, in a manner 

 similar to that in which the Tcretriosoma beetles above 

 described were found, and was more especially abundant 

 in the galleries containing numerous S. anale larvae ; it 

 is not improbable that its attacks are confined to these 

 latter, and perhaps to their pupae. 

 Alindria orientalis, var. parallela, Lev. (p. 114).— An elongate, parallel, black 



beetle, with the thorax smooth and shining, uniformly punctate, truncate in front, and sinuate, 

 constricted behind. Elytra broader than thorax at its basal part, 

 apices rounded, the suture gaping, prominently striate-punctale. 

 Length, 13 mm. to 14 mm. 



Alindria orientalis, Redtenb. (p. 114).— Larger than 

 last, rather broader. The elytral striae broader, more prominent, 

 and punctate. Legs stout ; front tibiae toothed on outer edge. 

 Length, 14.5 mm. to 15.5 mm. 



Larvae.— Two forms of larvae have been taken : {a) White, 

 with black head and thorax, two black spots placed transversely 

 on second and third thoracic segments, and a black patch on 

 abdominal segment dorsally ; three pairs of thoracic legs ; length, 

 I J in. {b) Head black, first two thoracic segments white, rest 

 white with a dark-coloured roundish patch on third-eleventh 

 segments; length, ijin.

Life Histories.— These two beetles are the com- 

 monest of the predaceous foes of Sinoxylon crassum 

 and 5. anale at Changa Manga in the Punjab. In 



May 1905 the beetles were taken literally in hundreds in the tunnels of the
