CONOSOMA. 315 
5. Conosoma ornatum. (Tab. VII. fig. 15.) 
Ferrugineum ; antennis fuscis, basi pedibusque testaceis, capite thoraceque in medio fuscescentibus, elytris 
nigris, fascia irregulare basali rufa, abdomine variegato ; thorace parce punctato, basi truncato, angulis 
posterioribus subobtusis. 
Long. 4 millim. 
Hab. GuaTeMaLa, Cerro Zunil 4000 to 5000 feet, Guatemala city, Capetillo (Cham- 
pion); Panama, Los Remedios (Champion). 
Rather slender ; antenne moderately long, much thickened outwards, dark in colour, 
with the basal joints pale, the two or three penultimate joints not so long as broad ; 
the terminal joint large. Head more or less infuscate, usually paler in front. Thorax 
about as long as broad, but little rounded at the sides, moderately narrowed in front; 
the base not sinuate till quite close to the hind angles, these being very minutely 
prolonged backwards, and not rounded ; the sides are broadly pale, the middle dark, 
the surface rather sparingly punctate. Elytra evidently longer than the thorax, rather 
more closely punctate than it, black with a broad irregular basal pale fascia. Hind 
body slender, red, more or less marked with black. Mesosternal carina slightly elevated 
behind, almost wanting in front. 
The small series of individuals of this species show some variation. Seven individuals 
from Guatemala agree closely except that the breast is either blackish or red, 
probably dependent on maturity, and that the infuscation of the thorax and segments 
of the hind body is variable in degree: an eighth individual, from Capetillo, has the 
antenne paler and more slender, and the variegation of the elytra much less distinct, 
while the pair from Panama have the antenne rather more slender and the terminal 
joint quite pale. The individual delineated on the Plate is from Cerro Zunil. 
6. Conosoma subornatum. 
Fusco-ferrugineum; antennarum basi pedibusque testaceis, elytris ad basin minus argute rufo-maculatis; 
crebrius punctatum; antennis articulo penultimo haud transverso. 
Long. 33 millim. 
Hab. GuatEMALA, Capetillo, Guatemala city, Zapote, Aceituno, Purula, San Isidro 
1600 feet (Champion); Nicaracua, Chontales (Janson). 
Antenne rather slender; the tenth joint about as long as broad; terminal joint a 
little paler towards the extremity. Thorax with the base only indistinctly sinuate on 
each side, the hind angles scarcely projecting backwards, minutely rounded; it is of 
fuscous colour, more or less vaguely ferruginous about the sides. Elytra only as long 
as the thorax, with a large vague transverse red mark at the base, not extending to the 
outer margin. Hind body fuscous, with each segment ferruginous behind. Meso- 
sternal carina only slightly prominent. 
The unique individual from Nicaragua is very pallid and immature, and it is not 
quite clear that it is really conspecific with the Guatemalan specimens.
