Description. brown. Prothorax with anterior margin 



rounded and tuberculate, disk very convex 



medianly ; anterior three-fourths roughly tuberculate and asperate, 



the tubercles placed at regular re'atively wide intervals on anterior 



portion, closing up behind : posterior fourth finely rugose-punctate. 



Elytra rugose and striate, the sides straight, decHvous apically ;

and legs yellow, punctate, pubescent. Length 1.5 mm. The only 



specimen I have seen is in too poor condition to enal)le the species to 



be described in detail. 



Specimens of this minute scolytid were taken from galleries beneath 



the bark in the bast of a felled and recently dead 



Life History. Erythrina subcrosa tree in the middle of February 1902 



by Babu B. Sen Gupta, at the time a student at the 



Imperial Forest School at Dehra Dun. The beetles were almost mature 



and ready to issue in the spring. They originated from eggs laid by the 



last generation of the insects, which probably oviposited some time in the 



autumn of igoi.

Cryphalus sp.

Life History. beetles so taken on 6 July 1902 were fully mature, the 



other was lighter-coloured and inmiature. All three 



beetles were dead. Beyond the fact that this insect infests this tree and 



its grubs feed in the bast layer, as was evidenced by their excavations, 



nothing appears known.
