Genera and Species of Coleoptera. 31 
sions which are common to many Colydide. There is some doubt 
as to the tarsi: the anterior has five joints, although the basal one 
is only visible from beneath, as shown in the right-hand figure 
(Pl. III. fig. 1); but the remainder appear to have only four. The 
head, from its great breadth, appears to be only very slightly ex- 
serted. I have five or six species of this subfamily in my collection, 
which I have not yet examined. 
Crine cephalotes. (Pl. III. fig. 1.) 
C. ferruginea, nitida; capite prothoraceque vage, elytris seriatim punc- 
tatis. 
Hab. Ega (Amazons). 
Short, depressed, ferruginous, shining, the sides nearly straight, but 
gradually becoming narrower from the eye to the last abdominal seg- 
ment; head and prothorax with large, scattered, shallow punctures, 
the latter with a smooth central ovate space, slightly contracted ante- 
worly, extending from the base to the fore margin, and surrounded by 
a line of strong punctures ; scutellum nearly triangular; elytra abruptly 
rounded at the apex, with about seven rows of oblong punctures on 
each; pygidium strongly punctured; legs and body beneath ferru- 
ginous ; abdomen, except the basal segment, strongly punctured; eyes 
dark brown ; head large, triangular, deflexed, with a groove extending 
from the insertion of the antenne to the mandibles; epistome very 
small, concealing the lip; eyes lateral, prominent; antennee exposed 
at the base, twelve-jointed, the first large, obconic, the second and 
third successively smaller, the fourth to the ninth inclusive subequal in 
length, but gradually becoming more and more transverse, the tenth 
largest of all, and with the gradually diminishing eleventh and twelfth 
forming a shortly ovate club; palpi short, stout; labium oblong, 
mentum transverse ; prothorax transversely quadrate ; elytra as broad 
as the prothorax at the base; legs short, cox subremote, interfemoral 
process truncate anteriorly ; tibiz trigonate, the border at the distal end 
spinous beneath; tarsi short, the anterior five-jointed, the last as long 
as the rest together; abdomen with five segments, the three interme- 
diate very short and equal. Length 1 line. 
Puormesa [ Colydiidee ]. 
Caput insertum, subquadratum, ante oculos dilatatum. Antenne basi 
tectze, clava biarticulata, sulcis antennariis brevibus. Mentum qua- 
dratum. Marille lobis angustatis. Prothorax transversus, antice 
sinuatus, marginibus dilatatis, crenatis. Zbie lineares, breviter calca- 
rate. Zarsi articulis tribus primis brevibus. 
It will be seen from these characters that this genus differs but in 
few particulars from Bitoma; the presence of antennary grooves and 
the dilated margin of the prothorax are, however, of too much im-
