EUDEROPUS.—ANOBOCLUS. 625 
8. Euderopus chetophorus, sp.n. (Tab. XVIII. fig. 25.) 
Ovalis, convexus, piceus, antennis pedibusque rufis, supra pube grisescente setisque nigris variegatus ; elytrorum 
punctatura seriata. 
Long. 23 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species is very remarkable on account of the variegate shimmer of the upper 
surface and the beautiful regular development of the system of sete. These are 
arranged in rows, and each seta is directed backwards, so that when looked at from the 
front they appear on the thorax and elytra like fine raised lines; the sete on the head 
are very conspicuons. The minute pubescence that gives the variegation to the surface 
varies in pattern according to the direction it is viewed from. In other respects the 
species comes close to 4. setosus. ‘The long slender hind tarsi are remarkable. Five 
specimens. 
ANOBOCQG:LUS, gen. nov. 
Corpus sat elongatum et transversim convexum, pube subtilissime vestitum, lineis pubescentie subtilissimis 
exaratum. Pedes crassiusculi, tibie posteriores tarsis certe duplo longioribus. Acetabula intermedia et 
posteriora lineis postice vergentibus munitis. Antennarum clava valida, triarticulata. 
I establish this genus for some little insects apparently of the greatest rarity, so that 
I cannot give the characters very fully. The three highly developed pairs of lines on 
the under surface are very remarkable; the pair behind the posterior coxe extend to the 
outer edge of the abdomen. The comparatively thick legs are very different from those 
of Euderopus. ‘These structural peculiarities, in conjunction with the three-jointed 
club of the antenne, distinguish Anobocelus from all the other genera of Biphylline. 
The prosternal process seems to differ a little in the two species, but the front coxe are 
considerably less approximate than they are in Euderopus. 
1. Anobocelus optatus, sp. n. 
Ferrugineus, pube minutissima subflavescente vestitus, vix perspicue sculpturatus; prothorace lineis decem 
subtilissimis exarato. 
Long. 3 millim. 
Hab. Mxrxico, Vera Cruz (Sallé). 
Head broad, with large eyes. Thorax strongly transverse; a good deal rounded 
at the sides, front angles scarcely prominent, surface densely but very indistinctly 
punctured, and with ten perfectly straight very fine lines, of which the four on the 
middle part are more approximate. Elytra with the sculpture extremely minute and 
obscure, covered with an extremely minute pubescence, and having on each about ten 
perfectly straight lines caused by minute depressed sete. Two specimens, both in 
fragments.
