626 CRYPTOPHAGID &.—LATHRIDID. 
2. Anobocelus championi, sp.n. (Tab. XVIII. fig. 26.) 
Fuscus, opacus, pube minutissima vestitus, vix perspicue sculpturatus; prothorace elytrisque lineis subtilissimis 
exaratis. 
Long. 34 millim. 
Hab. Guatemata, Zapote (Champion). 
We have only one specimen of this species: as it is worn and somewhat damaged, 
I cannot speak with precision as to the details of pubescence and sculpture. ‘Though 
very similar to A. optatus, I do not doubt that it is distinct. ‘The thorax is a good deal 
sinuate at the base on each side, and the lines of pubescence are very obscure. ‘The 
scutellum is strongly transverse, and there is an impressed line on each side of it, 
giving the appearance of a basal margin along the middle part of the elytra. The 
elytra have regular series of obscure punctures. 
Fam. LATHRIDIIDE *. 
The Lathridiide include, as at present composed, about 400 species, all minute 
insects, The family is, however, unsatisfactory, inasmuch as it contains heterogeneous 
elements, and at the same time is not satisfactorily distinguished from either Colydiide 
or Erotylide. It is supposed to be characterized by the 3-jointed tarsi, but as some 
of the Colydiide have 3-jointed feet it is evident that the characters require recon- 
sideration, and I am of opinion that, if retained as distinct from Colydiide, at any rate 
the whole of the Merophysiine should be removed from Lathridiide to the family 
in question. . 
The North-American species have recently been monographed by H. C. Fall, and I 
have followed his arrangement and pretty nearly his generic views. We have received 
only a small series of about twenty species, but I have no doubt that these obscure 
little insects are really much more numerous in our region. Fall recognizes fully 100 
N.-American species. 
Subfam. MEROPHYSIINE. 
HOLOPARAMECUS. 
Holoparamecus, Curtis, Ent. Mag. 1. p. 186 (1833). 
This genus of minute Coleoptera comprises about twenty species, and is widely 
distributed, though most of the described forms are from the Palearctic Region. Fall 
recognizes six species as found in the United States.
