This familiar genus is almost confined to the temperate regions of the northern 
hemisphere. One of the North-American forms extends southwards to just within our 
limits. Anaspis has been divided into several subgenera by Emery ; the single species 
here recorded belongs to his section “ Anaspis sensu stricto.” 
1. Anaspis atrata. 
Anaspis atra, Lec. Aun. Lyc. N. York, v. p. 157 *, & Proc. Acad. Phil. xiv. p. 457; J.B. Smith, Trans. 
Am. Ent. Soc. x. p. 77, t. 1. fig. 20° (nec Fabr.). 
Hab. Norra America, California! 2, Colorado ?.—Mexico, Northern Sonora (Morrison). 
Specimens received from the late Mr. Morrison are apparently referable to this 
species. Neither Leconte nor J. B. Smith mention the sex of the examples described 
by them: in the male of the Sonoran insect the fifth ventral segment is cleft down the 
middle from the apex nearly to the base, and from the apex of the third segment two 
long slender appendages are extruded, these being very narrowly separated and resting 
parallel to each other along the centre of the segments 3-5, and extending to the apex, 
the space between them smooth but not depressed. The insect is closely allied to 
A. frontalis (Linn.) and other Kuropean species. 
Group MORDELLIDES. 
This group is very largely represented in Central America, the majority of the 
species, as in other regions, belonging to Mordella or Mordellistena. One remarkable 
new genus is added, this being without the characteristic anal style, and thus differing 
from all other known members of the group. Most of the Central-American repre- 
sentatives are described as new, two only having hitherto been recorded from within 
our limits. In the descriptions of the new species the length-measurements are taken 
from the front of the thorax to the end of the elytra and from the front of the thorax 
to the tip of the pygidium when the insect is extended; and the breadth-measurements 
from the widest part of the thorax. 
COTHURUS. 
Last joint of the maxillary palpi exceedingly broad, large, and securiform, its apical side concave and nearly twice 
the length of the outer side, the latter not much shorter than the inner side; eyes finely granulated ; 
scutellum trapezoidal, twice as broad as long, a little produced in the middle behind; the last dorsal 
segment obtuse at the apex, not prolonged into a style; metasternum sharply transversely keeled in front 
immediately behind the widely separated middle coxa, its anterior edge vertical, the keel extending outwards
