CEPHALODINA.—CIRRHICERA. | 213 
The combination of enlarged head in both sexes, excessively developed in the female, 
and the absence of the usual sharply defined line or carina on the sides of the elytra, 
effectually distinguishes this genus from Amphionycha, with which it agrees in the pro- 
portions and clothing of the antennal joints. The pubescence which clothes the upper 
surface of the joints is very short and incumbent. The body is much less elongated 
than is the rule in Amphionycha. The enlarged head alone would not be a sufficient 
generic character, as it is frequent, sometimes in the female only, in Amphionycha. 
Three species of the genus are known, from Central America and the northern parts 
of South America.

Breviter cylindrica, robusta, sparsim erecte pilosa, subtus nigra, griseo pubescens, supra capite et thorace albis 
opacis, illo epistomate, plaga triangulari verticis vittaque utrinque pone oculum, hoc macula rotundata 
disci, nigris; elytris nigris, apice griseis ; antennis nigris, articulis 5° et 6° totis, 4° apice 7°que basi albis ; 
thorace breviter cylindrico, basi paullo angustato et depresso dorso antico convexo; elytris subtiliter nigro- 
pubescentibus indistincte punctulatis; pedibus nigris, femoribus 4 anticis basi flavis.. 
Long. 53 lin. 9. 
Hab. Nicaragua, Chontales (Belz). 
One example only of this remarkable insect was found by Mr. Belt. It differs from 
the other known species, C. capito and C. megacephala, in the head having no trace of 
concavity between the eyes. 
CIRRHICERA. 
Cirrhicera, Thomson, Archiv. Ent. i. p. 8309; Lacordaire, Gen. Col. ix. p. 892. 
Hemilophus (partim), Castlenau, Hist. Nat. Ins. ii. p. 489. 
_ Four species of this pretty genus, peculiar to Central America and Mexico, have pre- 
viously been described. Lacordaire remarked that it differs in nothing from the typical 
Amphionyche except the long hair-tufts on the fifth and sixth antennal joints; it 
must be added that it also differs in the elongation of the fourth joint, which is but little 
shorter than the third. The sides of the elytra are more or less distinctly carinated ; 
and the high and vertical epipleure are furrowed with longitudinal punctured strie. 
1. Cirrhicera leuconotus. 
Hemilophus leuconotus, Castlenau, Hist. Nat. Ins. ii. p. 489°. 
Hab. Mexico, Orizaba (Sallé).
