LONGICORNIA. 343 
Hab. Guatemaa, Chinautla (Salvin), Las Mercedes, Volcan de Atitlan, Cerro Zunil 
(Champion); Panama, Bugaba ( Champion).—Sovutu America, Rio Janeiro (Squires). 
Possibly the male of A. muticus, Thoms., notwithstanding the great difference in the 
form of the pro- and mesosterna. 
I have not yet seen examples of A. consors from the other localities in which 
A. muticus is known to occur, viz.:—Amazons, Volcan de Chiriqui, Chontales, and 
Mexico. 
Mr. Squires took near Rio Janeiro specimens of a form very similar to A. consors, 
but having the strongly convex mesosternum and other structural characters of 
A. muticus. This is evidently the A. preustus, Thomson, and is more probably the 
true male of A. muticus. 
14. Adetus curtulus. 
A. mutico affinis, multo minor, capite thoraceque relative multo longioribus. Subcylindricus, brevis, obscure 
fuscus, tomento subtili fulvescenti-fusco vestitus, elytris guttis numerosis, hic illic confluentibus, atro-fuscis, 
guttaque angusta utrinque sublaterali paullo post medium alba, thorace lateribus pallide fuscis; capite 
thoraceque grossissime irregulariter punctatis; elytris apice brevissime oblique truncatis, basi lineatim, 
lateribus et apice confuse, grosse punctatis, versus suturam punctis multo rarioribus; ventre immaculato ; 
mesosterno elevato, convexo, antice oblique declivi. 
Long. 23-3} lin. 
Hab. Panama, Bugaba (Champion). 
Differs from A. muticus by the head and thorax together being as long as half the 
elytra (in that species they are not one third the elytral length), also in wanting 
the black apical spot, which is replaced by a cluster of large punctures coloured 
blackish, and in its numerous dusky markings. 
15. Adetus postilenatus. 
A, costicolla proxime affinis, quoad formam similis; differt elytrorum apice fusco-nigro maculaque utrinque 
reniformi anteapicali sordide ochracea. Cylindricus, sordide fulvo-fuscus ; thorace indistincte ochraceo 
vittato, grosse subconfluenter punctato ; elytris apice obtusis, punctis minoribus et majoribus distantibus 
lineatim digestis ; mesosterno convexo et porrecto, antice emarginato, verticali. 
Long. 3-53 lin. ¢ Q. 
Hab. Guatemata, Mirandilla (Champion); Panama, Bugaba (Champion). 
16. Adetus mucoreus. | 
Subcylindricus, fuscus sed castaneo-rufus; capite fulvo-, thoracis lateribus plagaque elytrorum anteapicali 
cretaceo-, tomentosis; thorace grosse sat confertim punctato; elytris apice fere integris, suturam versus 
lineatim, latera versus confuse, punctulatis, stria suturali impressa a medio usque ad apicem; corpore 
subtus griseo-pubescenti; mesosterno leviter arcuato, supra plano.
