138 Mr. F. P. Pascoe on the Colydiidee 
Oblong-ovate, dark brown; head punctato-squamose; antennz and 
palpi ferruginous; prothorax slightly rounded at the sides, scarcely 
contracted at the base, covered with erect greyish scales; elytra a little 
raised towards the base, very slightly emarginate near the apex, punc- 
tato-sulcate, the interstices with scattered greyish scales; body beneath 
dark brown, subnitid, with a few large punctures; legs reddish pitchy. 
Length 2+ lines. 
The small size and “ peaked ”’ elytra will distinguish this species. 
Besides the three members of this genus described in this work and 
the typical Dastarcus porosus of Mr. Walker, I have also three very 
distinct species from India, and a fourth, which, however, departs 
in some respects from the usual characters of the genus, from Fiji. 
Trachypholis equalis. 
T. parallelo-oblonga, fusca, opaca, squamis albescentibus parce -tecta; 
antennis pedibusque ferrugineis. 
Hab. Timor. 
Parallelo-oblong, dark brown, opaque, rather sparsely covered with 
very small, erect whitish scales; head rounded anteriorly; prothorax 
very transverse (twice as broad as long); elytra with the scales scarcely 
arranged in lines; body beneath black, subopaque, with appressed, 
greyish sete ; antenn and legs ferruginous, covered with pale greyish- 
white sete. Length 3 lines. 
Trachypholis, Er. (Naturg. Ins. Deutschl. iti. p. 257) is synony- 
mous with Tarphiodes, § I., Woll. (huj. op. i. p. 372). The first- 
mentioned author compares it to Colobicus, the latter to Tarphius, 
at the same time placing with it, but under another section (“ sub- 
genus” Tarphiosoma), Tarphiodes Indicus, which I regard as being 
generically very distinct, and to which the name of Tarphiosoma may 
be applied. It will be seen that I have placed Tvrachypholis with 
the Bothriderine, although the posterior coxe are only moderately 
apart and the basal segment of the abdomen is only a degree larger 
than the second ; but its affinity to Dastarcus on the one hand, and 
through Tarphiosoma to Tarphius on the other, is too evident to 
admit of any other location. It is, however, to be observed that 
Erichson places the latter genus with the Synchitine, notwithstand- 
ing that its posterior coxee are widely remote. The species described 
above is characterized principally by its dull, opaque colour and the 
more regular distribution of its scales, which are scarcely arranged 
in lines on the elytra as in four other species now before me, The 
late M. Mouhot sent to this country a considerable number of in- 
dividuals of a species of this genus, which, through the kindness of
