but the distinct triangular though small tooth in the emargi- 

 nation of the mentum may be a specific character, and I have 

 seen numerous examples from the neighbourhood of Bangkok 

 (Siam) without any admixture of the more densely punctured 

 form.

P. (?) semilaevi affinissimus, sed multo major, capite comparate 

 majori et post oculos latiori. Nigerrimus, nitidus, elytris sicut in 

 P. sublaevi antice sparsim, postice dense, punctulatis, palpis 

 apice antennisque partim piceo-rufis. Thorax baud diversus. 

 Elytra profundius striata, interstitiisque convexioribus 3.'°, 5.*°

 leviter prominenti baud vero dentatura. — Long. 14-15 millim. 9 .

Two female examples only, compared in the above description 

 with individuals of the same sex of P. semilaevis. 



The four preceding with another more widely-distributed 

 species in S. Eastern Asia (^), form a group somewhat distinct 

 from the more typical Platymetopi in their elongate form (re- 

 sembling the larger Ophoni) and the finer and more smoothly 

 recumbent pubescence. The presence of a small but distinct

This species corresponds with the short and very insufficient description of Mac 

 Leay rather better than does Gnathaphanus dispellens , which it appears that 

 Chaudoir determined as the Harpalus punctilabris of the Anniflosa Javanica. It 

 may be, however that P. (?) gnathaphanoides is really the species on which he 

 intended to found his genus Trichoglottus .
