Hab. Nicaragua, Chontales (Belt 1, Janson). | 
Differs from A. druryt in the posterior yellow belt of the elytra being much more oblique, 
by the fine grey pile of the elytral surface, and the black margins of the yellow belts. 
5. Amphionycha pluricostata. 
Valde elongata et convexa, subtus nigra, supra macula frontali, vittulis quatuor verticis, thorace elytrorumque 
dimidio basali coccineis vel fulvis, thorace vitta dorsali et macula utrinque subbasali elytrorumque humeris 
nigris ; capite valde angustato et retracto; thorace antice attenuato; elytris apice late rotundatis, dorso 
punctato-striatis, interstitiis convexis, lateribus valide bicostatis, costis parallelis a callo subfalcato humerali 
usque fere ad apicem excurrentibus ; antennis nigris (  ), quam corpus multo brevioribus ; pedibus nigris. 
Long. 73 lin. Q. 
Hab. GuateMAta, Purula (Champion). 
6. Amphionycha, obesa. 
Q. Valde elongata et convexa, piceo-fusca, abdominis segmentis tribus apicalibus cinereo-flavo tomentosis, 
fronte thoracisque vitta laterali lata (postice dilatata) cinereis; elytris sutura, margine laterali lineaque 
discoidali obscure fulvis ; capite angusto, retracto, inter oculos concavo; thorace antice attenuato, medio 
utrinque paullulum tumido; elytris apicem versus late rotundatis margineque apicali breviter sinuato- 
truncatis, dorso subtilissime punctulatis, utrinque costulis duabus vix elevatis ; antennis quam corpus multo 
brevioribus, nigris ; femoribus basi pallidis.

Var. Paullo angustior, nigerrima, thorace vitta lata laterali cinerea, cacteris ut in typo. 
Hab. Mexico, Omealca (Sallé); var. GuaTeMaLa, Purula (Champion). 
- Both the examples above described appear to be females; the Mexican one bears the 
name in the Sallé collection of A. collaris, Chevr. The middle tibiz are quite free 
from notch on the outer edge. Although evidently closely allied to A. pluricostata, 
and not generically separable from it, the lateral carine are but feebly elevated, and are 
obsolete beyond the middle of the elytra, and the punctuation of the surface is extremely 
minute and scattered.
