SPERMOPHAGUS. 501 
tato, ad latera punctis majoribus adjectis ; scutello oblongo, apice tricuspidato; pygidio macula magna 
fusca griseo-marginata ornato, 
Long. 54-73 millim. 
Hab. Britisu Honpuras, R. Hondo (Blancaneaur); GuatemMata, San Gerdnimo, 
Chacoj in the Polochic valley (Champion); Panama, Caldera, Volcan de Chiriqui 2500 
to 4000 feet, Bugaba (Champion). 
Antenne ferruginous, feebly serrate ; third joint twice as long as the second, the tenth 
a little longer than broad. Head broad; eyes large, very coarsely facetted, only mode- 
rately distant in front. Thorax strongly transverse, moderately narrowed in front, the 
front margin broader and less rounded than usual, the surface very densely and finely 
punctured, with some larger punctures at the sides, covered with fine griseous pubes- 
cence, and sprinkled with a few minute white marks. Llytra ferruginous, more or less 
infuscate, and with some black marks, covered with a very fine pubescence of a griseous 
colour, more or less marbled with white. Pygidium nearly entirely occupied by a large 
oval mark of dark fuscous colour, a little darker above, and surrounded by dense pallid 
pubescence. Inner carina of the hind margin of the posterior femur distinctly emar- 
ginate at the extremity. Front cox widely separated, the prosternal process short, 
received into a definite cavity at the apex of the mesosternum. This species agrees in 
many respects with Gyllenhal’s description of S. cistedinus, but not with examples from 
Cuba so named by Jekel in our national collection at Kensington. 
20. Spermophagus marmoratus. (Tab. XXVI. fig. 24*.) 
Latior, ovalis, niger, griseo testaceoque marmoratus, prothorace elytrisque testaceis nigro marmoratis ; pygidio 
macula magna ovali fusco-brunnea notato. 
Long. 7 millim. 
Hab. Muxico (Sallé); Panama, Volcan de Chiriqui, Bugaba (Champion). 
Head black, broad and short ; eyes moderately large, finely facetted, widely separated. 
Antenne black, moderately broad, feebly serrate, the tenth joint rather longer than 
broad. Thorax transverse conical, pale, without distinct punctuation, densely pallid- 
pubescent, with some indistinct fuscous nebulosities near the front, the surface depressed 
in front of the scutellum; this latter oblong, rather short, rounded behind. Elytra 
similar in colour to the thorax, densely pubescent, so that the striation is quite indi- 
stinct, on the apical half largely marked with black in an irregular manner. The large 
pygidial mark is formed of dense pubescence, and is so shaded that when looked at 
from behind it has the appearance of a cavity extending to the interior of the insect. 
Front and middle legs yellow; hind femora black, yellowish at the apex, the tibie 
variegate. 
This is a remarkably distinct species: the prosternum widely separates the front legs, 
* On our Plate the numbers of the figure of this species and of S. ¢rroratus are erroneously given as 25 and 26 
instead of 24 and 25 respectively, though correctly given below.
