sinuated rows, with the interstices aliitaceous; its legs are 

 very short, and the apical joint of its antennae is much 

 elongated. 



17. Trichopteryx Waterhousii, Matthews, £nt. Mo. 



Mag. vol. ii, p. 244 {described). 



Described from two examples in Mr. G. R. Waterhouse's 

 collection, taken many years ago, and of which the exact 

 locality is unregistered. 



It appears to be allied to T. Chevrolatii {jiygmcBa, Er.) 

 and T. Guerinii, but to be distinguishable from these and 

 all other species of the genus by its oblong, sub-parallel, 

 somewhat depressed build, dull black head and thorax, and 

 testaceous elytra, and by the sculpture of its thorax, which is 

 covered with small distinct tubercles, irregularly arranged in 

 close rows, with the interstices slightly alutaceous. 



18. Trichopteryx Jansoni, Matthews, Ent. Mo. Mag. 



vol. ii, p. 245 {described). 

 Described from a single specimen taken some years ago by 

 Mr. Matthews near Gumley, according to whom it resembles 

 the Ceylonese species T. invisibilis, Nietner, more than any 

 other, but may be readily distinguished from all by its sub- 

 parallel, cylindrical form, very wide head, and deep black 

 colour. Its thorax appears to be ornamented with remote 

 irregular sinuated rows of tubercles, the interstices being 

 deeply alutaceous and very shining j and its elytra are deeply 

 asperate in remote sinuated rows.
