HYDNOCERA. . 173 
Hab. Guatamaua, San Gerdnimo, Paso Antonio, Rio Maria Linda (Champion) ; 
Panama, David, Chiriqui (Champion). 
This little species is obscurely coloured and varied with pale and pitchy fuscous 
markings ; but of these the paler margins of the thorax and the spot at the base of the 
elytra (which at times leaves only the humeral point and the scutellum with an obscure 
cloud around it fuscous) are tolerably constant. The elytra cover the body, are a little 
narrowed behind, and have the apex scarcely, if at all, serrate. Their puncturing is 
close and intricate. The femora and tibie of the four hinder legs are widely clouded, 
with the knees and base paler in darker specimens; and in these the antenne have the 
apical joint fuscous; in other specimens both the antenne and legs are entirely 
testaceous. This insect has very much the facies of a small species of the eastern 
genus Stigmatium. 
There are ten specimens, of which seven are from San Gerdnimo, which I refer to 
this species. 
15. Hydnocera sordida. 
Sordide picea, obscura; antennis, palpis, pedibus anticis partim, elytrisque macula subhumerali flavis. Long. 
_ 4-53 millim. 
Var. Elytris vitta submarginali cum macula basali conjuncta flava. 
Hab. Mexico, Guanajuato (Dugeés, coll. Sallé). 
A species in many respects rather nearly allied to the preceding one. It differs in 
the head being more contracted behind, which gives the eyes a more prominent look. 
The thorax is wholly pitchy and, with the head, is very closely and subrugosely 
punctured. The elytra do not narrow behind so decidedly as in H. odscura; the legs 
are darker, the front and middle femora are obscurely red, with a dark cloud on their 
upper margins; the hind pair are usually wholly dark, or with the extreme base or the 
trochanter alone yellow. The elytra have a basal spot, and usually some trace of a 
vitta near the outer margin reddish yellow ; sometimes this vitta is prolonged to near 
the apex, and unites with the basal spot. The tip of the humeral callus is usually 
pitchy ; but in one specimen a rufous patch extends over the greater part of the base. 
The seven specimens in Sallé’s collection are numbered 584 and 585; but I consider 
them all referable to one species. 
Section Bi. Elytra covering the abdomen ; shoulders not carinate. 
16. Hydnocera corticina. (Tab. IX. fig. 6.) 
Elongata, subparallela, fusco-brunnea, crebre fortiter punctata ; elytris basi apiceque equali latitudine, in medio 
parum angustatis, fascia mediana ad suturam recurvata, indistincta, apiceque subalbidis ; pedibus variegatis, 
pallidis, genibus latius fuscis. Long. 5-7 millim. 
Hab. Mexico (Sallé); Guaremata, El Tumbador, Las Mercedes, Cerro Zunil 
(Champion).
