SOMATOXUS.—CYCLOCACCUS, 361 
Antenne yellow, with abrupt black club. Head and thorax moderately closely and 
coarsely punctate, very shining, black, the side-margins of the latter picescent, the 
base produced in the middle. Elytra with series of large punctures, which are finer 
behind ; the sides behind oblique, feebly sinuate; the sutural angle acute. 
We have received four examples of this species. Two of them I suppose to be males, 
as there is a minute barely perceptible denticulation of the lateral margins of the wing- 
cases behind ; but the front tarsi are not at all dilated. 
CYCLOCACCUS, gen. nov. 
Corpus breviter ovale, sat convexum, glabrum. Clava antennarum laxa. Labrum transversum, breve, 
integrum. Mandibule breves, sub labro omnino condite. Prosternum processu sat magno, apice 
rotundato. Mesosternum obsolete carinatum. Metasternum medio haud impresso, subtiliter margi- 
natum, margine inter coxas utrinque producto. Coxe intermedi et posteriores distantes. Tarsi 
sequales, omnes sublineares, paullulum dilatati. 
Cyclocaccus differs from Meoncerus in the short form, the less dilated tarsi, and the 
more widely separated middle coxe. In form it perhaps more resembles Padlodes, from 
which it differs by numerous characters, and notably by the more widely separated coxee. 
The antennary grooves are strongly convergent, and the short broad labrum has a small 
depression on the middle. The palpi are simple and quite short. 
1. Cyclocaccus monticola, sp. n. 
Subovalis, sat convexus, nitidus, piceus, supra nigro-piceus, antennarum basi, prothoracis lateribus pedibusque 
testaceis; antennarum clava nigra; prothorace levigato; elytris seriatim punctatis, interstitiis im- 
punctatis. 
Long. 4 millim. 
Hab. Guatemata, Quiche Mountains 7000 to 9000 feet (Champion). 
Head obsoletely punctate, deeply transversely impressed near the front. Thorax 
smooth and shining, black in the middle, broadly yellow at the sides, strongly trans- 
verse, much narrowed towards the front, a little curved at the sides; base nearly 
straight, rather narrower than the base of the elytra. Scutellum very broad, sinuate 
at the sides, very obtuse behind. Elytra with regular series of closely-placed punc- 
tures; interstices impunctate, the punctures of the series obsolete at the apex. 
Pygidium and under surface smooth and shining. Legs slender, rather long. In the 
male the anterior and middle tarsi are broader than they are in the female. 
Eight specimens. 
2. Cyclocaccus brevicollis, sp. n. 
Brevis, sat convexus, nitidus, testaceus, supra piceus, limbo dilutiore; antennarum clava nigra; prothorace 
fere impunctato; elytris seriatim punctatis, interstitiis obsolete punctatis. 
Long. 33 millim. 
Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion).
