i 7 4 FAMILY BOSTRYCHIDAE 



Scarites bengalensis, Dej.(p. 95). Elongate, black, with stout prominent mandibles 

 and striate elytra. Head broad, slopes forward, the front depressed on either side of a raised 

 median ridge, the depressions finely and longitudinally striated. Prothorax broader than head, 

 anterior margin concave, with a hue transverse depressed line just below margin ; posterior 

 outer angles obliquely truncate, sides straight ; disk convex, smooth, dull. Elytra strongly 

 striate, the striae parallel ; apices conjointly rounded, surface shining. Length, 15 mm. 



Life History. This beetle preys upon Sinoxylon anale in the sissu-tree. 

 I took specimens of the insect from beneath the bark of trees badly infested 

 by the bostrychid at the Changa Manga plantation in May 1905. The 

 beetle is quick in its movements. 



Morio subconvexus, Chand. (p. 96). Elongate, black, shining. Resembles the 

 Scarites superficially, but is broader, shorter, and more shining. Head flat, strongly impressed 

 dorsally, mandibles prominent. Prothorax wider than head, anterior angles sharp, sides 

 rounded, constricted behind ; disk moderately convex, a median longitudinal impressed line 



starting in anterior third and reaching base, with two elongate depressions 

 above base, one on either side. Elytra broader than prothorax, striate 

 longitudinally ; striae broad ; sides straight, constricted apically. 

 Length, 14 mm. 



Life History. The beetle preys upon Sinoxylon anale 

 and possibly upon S. crassnm. I took specimens in com- 

 pany with Scarites bengalensis beneath the bark of sissu- 

 trees at Changa Manga.

Trees Attacked. Anogeissus latifolia : Horai, Ku- 

 maun ; Acacia catechu: Thana (G. M. Ryan). 



Beetle. Very small, elongate, cylindrical. Black, moderately shining. Head finely rugose- 

 punctate. Prothorax convex, transversely ridged medianly, dropping away behind, where it is 



finely rugose-punctate ; anterior part coarsely rugose and rasp-like, 



Description. the prominences largest laterally and on highest portion of ridge ; 



four teeth, the inner three large and prominent, placed on either side 



laterally of anterior margin. Elytra widest apically, uniformly rugose-punctate ; punctures 

 largest near suture ; latter thickened and produced into two small sharp triangular teeth in 

 upper part of declivity. Length, 3.6 to 4 mm. 



In January 1902 Mr. G. M. Ryan, of the Indian Forest Service, for- 

 warded to me some specimens of this insect from Thana, 



Life History. Bombay, where he had found them tunnelling into 

 branches of Acacia catechu. About the middle of April 



1905 and middle of May 1908 I took the beetle tunnelling into cut poles and 

 felled logs of Anogeissus latifolia in the Horai sal forest in the Terai of 

 Kumaun. This insect was most abundant in April, which is apparently the 

 month in which it makes its first appearance of the year and lays the eggs 

 of the first generation. In May the beetles taken were mostly deep down 

 in the wood at the end of longish galleries which, after entrance into
