§ 3. Thorax somewhat distorted at the sides owing to the large size of the 
antennal cavity.—Species 36-41, 
‘The species of this section are more oblong in form than the others of the genus. 
36. Cryptorhopalum discedens, sp.n. (Tab. XIX. fig. 24, antenna.) 
Suboblongum, leviter convexum, nigrum, antennis, tibiis tarsisque rufis; parce subtiliter punctatum et 
pubescens ; antennarum clava magna, subovali. 
Long. 2 millim. 
Hab. Mexico, Teapa (H. H. Sinith). 
The club of the antenna is both long and broad, the terminal joint large, though a 
good deal smaller than the preceding one. There is scarcely any punctuation on the 
thorax, but there is a griseous pubescence at the sides. The elytra are finely and 
sparingly punctured, and have a scanty griseous pubescence, which is short and but 
little conspicuous. The punctuation of the abdomen is dense and fine, and the 
pubescence correspondingly conspicuous. The pubescence has a slight flavescent tint, 
and this makes the abdomen look tawny. One specimen. 
37. Cryptorhopalum amulg, sp. n. 
Oblongum, leviter convexum, nigrum, griseo-pubescens, antennarum clava fuscescente, tarsis rufis; crebre 
subtiliter punectatum, haud nitidum ; antennarum clava elongata. 
Long. 23 millim. 
Hab. Mexico, Amula in Guerrero 6000 feet (HZ. L7. Smith). 
More elongate than C. discedens, and readily distinguished by the more conspicuous 
punctuation and pubescence, and the different form and colour of the club of the 
antenna, which is narrower and more oblong than it is in C. discedens, and the two 
joints forming it are less accurately connected together. One specimen. 
38. Cryptorhopalum vestitum, sp. n. 
Suboblongum, nigrum, supra fuscescens, setosum, antennis pedibusque rufis, parce subtiliter punctatum ; 
maris antennarum clava maxima. 
Long. 3 millim. 
Hab. Guatemata, Purula (Champion). 
The pubescence of the upper surface is stiffer and rougher than usual in this species, 
and the ground-colour of the elytra is not pure black; the pubescence is griseous, with 
a slight flavescent tinge. The side of the thorax is strongly arched over the antennal 
fossa. The legs, including the femora, are red, the tibie and tarsi long and very 
slender. The large club of the male antenna is somewhat slender-oval, the first joint 
not quite twice as long as broad, the terminal joint large, rather more than half as 
long as the preceding one. ‘Two specimens.
