FAMILY COLYDIIDAE

Tkachypholis.. 

 Two species of this genus have been taken in the Burma forests. 



Trachypholis hispida, Weber. 

 Reference — Weber, Obs. Ent. i, p. 38. 



Habitat. — Upper and Lower Burma, Tenasserim. 



Trees lYif^si^d.—Anogeissus latifolia (Tharrawaddy) ; Teak {Tectona 

 grandh). Mohnyin Forest, Katha ; Wutgyi, Salween River, Tenasserim. 



Beetle — Ovate, flat, the edges of thorax and elytra set with a spiny fringe of hairs. Black. 

 Prothorax wider than long, depressed laterally and margined ; rugose-punctate. Elytra with 

 sides straight to apical fourth, thence constricted and conjointly rounded ; surface broadly 

 striate and strongly punctate, the punctures large. Length, 6 mm. 



Habits. — This beetle was first taken on 22 January 1905, beneath the 

 bark of an Anogeissus latifolia tree in Tharrawaddy which was badly infested 



by several bark- and wood-boring beetles, the chief of 

 which was Platypus rectangulatus (p. 623). The insect 

 is undoubtedly predaceous, and probably chiefly on 

 the Platypus, in whose tunnels it was taken as well 

 as beneath the bark. The beetle is very active and 

 a quick runner. The following month (19th) I took 

 the insect beneath the bark of a large standing 

 girdled teak in the Kadu depot in Katha in Upper 

 Burma. Here I noted that the pupal chambers of 

 the beetles appeared to be in the inner bark of the 

 tree. On 7 March following I again took the beetle 

 from beneath the bark of a dead felled teak in a 

 paddy clearing at Wutgyi on the Salween River in 

 Tenasserim. The Trachypholis is apparently pre- 

 daceous upon more than one species of insect.

Habitat. — Katha, Upper Burma. 



Tree Infested. — Wendlandia tinctoria. Mohnyin Forest. 



Beetle.— Larger and broader than last. Black with small 

 tufts of yellowish pubescence forming spots on thorax and 

 elytra. Sides of thorax are more

more sharply constricted, the apex 

 truncate ; elytra slightly convex on disk ; punctate, the punc- 

 tures arranged in longitudinal rows. Length, 8 mm. 



Habits. — I took a specimen of this beetle 



from beneath the bark of a large felled Wendlandia 



tinctoria tree in a clearing on Kadu Hill in the 



Mohnyin forests in Katha. The beetle was fully ^^^
