622 CRYPTOPHAGID. 
more external series present, but much masked by the short clothing, which, viewed in 
certain directions, is seen to have very fine lines of slightly more elevated pubescence 
in it. Two specimens. 
2. Diplocelus parvus, sp. n. (Tab. XVIII. fig. 24.) 
Ovalis, depressus, dense pubescens, fusco-rufus ; antennis piceis vel rutis; pedibus rufis; prothorace valde 
transverso, dorso parce punctato, lateribus crebre fortiter punctatis. . 
Long. 2-2} millim. 
Hab. Muxico, Cordova (Sallé); Guatemata, El Tumbador, Las Mercedes (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
Head broad and short; eyes less coarsely facetted than usual in the Biphylline. 
Thorax broad, extremely short, front angles but little produced, sides minutely serrate, 
no anterior margin, except behind the eye; there is some coarse lateral punctuation, and 
a fine raised line reaching the front margin at the extremity of the line behind the eye; 
the irregularly distributed punctures on the disc are but little different from the lateral 
punctures. The elytra have series of punctures much obscured by the short abundant 
pubescence. The tibiz are short and very slender. Seven specimens. 
I have placed as a variety of D. parvus four specimens from Cerro Zunil and Senahu 
in Guatemala, in which the form is narrower, the thorax less narrowed in front, and 
the punctuation on its disc scarcely visible. 
This species is somewhat aberrant, on account of the thin linear tibia, the small 
tarsi, and the somewhat more distinct, though short, mesosternal line. 
EUDEROPUS, gen. nov. 
Corpus ovale, pube setisque vestitum. Tarsi tenues, posteriores tenuissimi, lobis liberis wgre discernendis. 
Metasterno post coxas intermedias, et abdomine post coxas posteriores, lineis inscriptis munitis. 
These characters are sufficient to distinguish this genus. The lines behind the 
posterior coxe are found in Biphylius, as well as in Anobocelus, but from the former 
this genus is abundantly distinguished by the three-jointed club of the antenne, and 
from the second by the slender legs; the prosternal process is but small, and is bent 
up behind the coxz; the middle coxe are rather widely separated. ‘The character by 
which the genus will be most easily recognized is the extremely slender, hair-like, hind 
tarsi, in which it is difficult to see the divisions between the joints. 
1. Euderopus brevipes, sp. n. 
‘Ovalis, sat latus, niger; antennis pedibusque rufis; elytris seriatim fortiter punctatis, pube parum conspicua 
haud variegata vestitis, setis reclinatis sat elongatis.

We have only one badly-preserved example of this species; it is more like a
