490 Mr. 0. J. Gahan on the 



reddish brown from the base to a little beyond the middle, 

 and thence to the apex dark brown ; each marked with three 

 white spots on the posterior half — the first spot close to the 

 suture, the second almost touching the lateral carina, and the 

 third (which is the largest) placed very close to the apical 

 border; a faint white line, placed just above the lateral 

 carina, is to be seen on each elytron running from near the 

 base to a short distance beyond the middle. Antennae 

 slender, longer than the body in both sexes, black in colour, 

 with the seventh and eighth joints covered with white 

 pubescence. 



Heteroglenea, gen. nov. 



Allied to the genus Glenea, Newm., with which it has 

 many characters in common, but differing as follows: — Ante- 

 rior claw of all the tarsi in both sexes bifid, posterior claw 

 simple. Elytra witliout distinct lateral carinie, but furnished 

 instead on each side with an obtuse costa which reaches 

 neither the base nor the apex. This genus will include the 

 following two species, of which the first is to be considered 

 the type.

Hah. Siam and Burma. 



Thomson's description of this species is very brief, con- 

 sisting of two lines of Latin. I have fully described the male 

 sex in the place cited above, and a further reference to the 

 species, giving the synonymy and sexual differences, will 

 be found in the Ann. Mus. Civ. Genova, vol. xxxiv. p. 89. 

 Both in this species and the next the elytra are more parallel- 

 sided than is usual in the genus Glenea^ and, though truncate 

 at the apex, are not spined. 



2. Heteroglenea gleckoma, Pasc.

Hah. Matabello ( Wallace) ; Sumatra {Modi'gliani) ; Solo-

The division of the anterior claw of the tarsi is less evident 

 in this species than in the preceding one and might very 

 easily be overlooked ; this claw, when looked at from the
