APOCELLUS. 695. 
form of the peculiar lateral wings of the terminal segment of the male. The 
specimens in Sallé’s collection were separated as several species with MS. names of 
Fauvel attached. Erichson’s outline figure is not satisfactory, and we consequently give 
one taken from the well-developed male example found by Mr. Salvin. In Chevrolat’s 
collection two examples of an Apocellus are labelled as having been received from 
Erichson as A. sphwricollis; these, however, are a distinct species (A. nigriventris, 
Chevy. in litt.), and it seems as if Erichson’s figure had been made partly from one of 
these examples, and partly from A. sphericollis. This insect is very widely distributed 
in the Southern United States.

Hab. Norrn America, Louisiana !, California}, Arizona }.—Mzuxtco, Cordova (Hége). 
3. Apocellus cognatus. (Tab. XVIII. fig. 14.) 
Politus, rufo-testaceus, abdominis apice nigro, parce longiusque setosus, nitidus, impunctatus; prothorace sub- 
quadrato, basin versus leviter angustato. 
Long. 33-4 millim. 
Hab. Norra America, Opelousas in Louisiana (Sa//é).—Guatemata (Sallé), 
Champerico, Rio Naranjo, near the city of Guatemala, San Gerdénimo (Champion) ; 
Honpuras (Sallé); Nicaracua, Managua (Sal/é). 
Antenne elongate, thicker externally. Head large, subquadrate, broader than the 
thorax, truncate behind. Thorax rather broader than long, the sides nearly straight, a 
little narrowed behind. Elytra broad and short, much wider and a little longer than 
the thorax. Hind body broad. In the male the hind margin of the penultimate 
ventral plate is somewhat emarginate and very slightly deflexed in the middle, and the 
following segment is broadly but feebly impressed. 
This insect is allied to A. analis, Lec., but has a comparatively feeble development 
of the male characters. The examples from Guatemala city and San Gerénimo are 
darker in colour and have a decidedly greater development of the male characters ; 
they may be distinct but are in very decayed condition, and the dark colour may be the 
result of this. The unique exponent from Honduras is a very large male of dark 
colour, and it also may possibly be distinct. 
4, Apocellus muticus. 
Sat latus, politus, rufus; elytris dimidio apicali fusco, abdominis apice nigro; prothorace subquadrato, basin 
versus angustato. 
Long. 33 millim. 
Hab. Mexico, Vera Cruz (Hoge). 
Very similar to A. analis, but the thorax is narrower, and not broader than long ; the 
basal half of the wing-cases pallid, the apical half fuscescent. The male characters
