EUDEROPUS. | 623 
Gonicelus than the others of the genus, and has the tarsi less elongate, though very 
slender; the series of punctures on the elytra are also more distinct. The antenne are 
short. The thorax is much narrowed in front, and has a fine raised line parallel with 
its margin; there is no second lateral line, but there is an obscure anterior marginal 
line. One or two of the series of punctures near the suture on the elytra are 
obliterated, but the other punctures are rather large. The prosternal process is very 
minute, and the femora scarcely reach the sides of the body. The hind tarsi, though 
not very long, are extremely slender. 
2. Kuderopus perbrevis, sp. n. 
Breviter ovalis, convexus, breviter pubescens, opacus, fusco-ferrugineus; antennis pedibusque rufis; elytrorum 
seriebus punctorum obliteratis. 
Long. 2 millim.

This species differs from all the others of the genus, except. L. microps, by the very 
short form, so that it is much attenuated in front and behind. ‘The head is small; the 
anterior marginal line of the thorax is quite distinct; the sete on the elytra are but 
little developed, and the series of punctures are very much obliterated ; two series are, 
however, quite distinct just behind the shoulder, though the punctures are small. One 
specimen from each locality. The Mexican one is in a very bad state of preservation. 
3. Euderopus microps, sp. n. 
Breviter ovalis, convexus, pubescens, subopacus, ferrugineus; antennis pedibusque testaceis ; elytrorum seriebus 
punctorum subtilibus, seriebus internis obliteratis. 
Long. 1? millim. 
Hab. GuareMata, Panima in Vera Paz (Champion). 
This is the smallest of the Biphylline [ have seen, and it has a smaller head than 
any of its allies. The thorax is excessively short. The two internal series of punctures 
on the elytra are obliterated, but the others can be seen for most of the length. ‘Two 
specimens. 
I have treated as a variety of EZ. microps a single specimen from the Volcan de 
Chiriqui; it isslightly larger, and the punctuation and pubescence are a little different. 
4, Kuderopus unicolor, sp. n. 
Ovalis, convexus, brunneo-ferrugineus; antennis pedibusque rufis; elytrorum punctis seriatis tantum post 
humeros conspicuis. 
Long. 24, lat. 13 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Head rather broad (for this genus). Thorax greatly narrowed in front, the raised 
line parallel with the margin very distinct, the sculpture very indistinct in consequence
