ANTHONOMUS. 177 
Hab. Panama, Volcan de Chiriqui and Caldera 2000-4000 feet (Champion). 
Two males and three females. Very like various similarly coloured species of Apion 
in general facies, and easily identified by its blue elytra, the sparse grey pubescence, 
and the elongate anterior legs, the anterior femora dissimilarly coloured in the two 
sexes. 
A. sulcipygus-group. 
88. Anthonomus sulcipygus, sp.n. (Tab. X. figg. 17,174, 3.) 
Subovate, varying in colour from nigro-piceous to ferruginous, the anterior legs and the knees and tarsi of 
the other two pairs in great part piceous or black in dark individuals; sparsely clothed with grey or 
yellowish pubescence, which is condensed on the scutellum and along a median line on the prothorax, 
the vestiture of the under surface grey or whitish. Head rugulosely punctate, foveate above the eyes, 
the latter large and prominent, and not very widely separated ; rostrum moderately curved, considerably 
longer than the head and prothorax, seriate-punctate, smoother at the tip, the antenne inserted at about 
one-third from the apex in the ¢, and at a little before the middle in the 9 , the funiculus slender, 
joint 1 about as long as 2-4 united. Prothorax transverse, rounded at the sides, feebly constricted and 
much narrowed in front, densely, rugulosely punctate. Elytra gibbous, much wider than the prothorax, 
moderately long, feebly transversely depressed below the base, the humeri rounded; deeply punctate- 
striate, the interstices strongly convex and minutely punctate. Prosternum slightly emarginate in front, 
Legs elongate, the anterior pair especially ; femora each with a long, acute tooth, the anterior pair 
usually with a minute tooth exterior to it; anterior tibie strongly sinuate within ; tarsal claws with a 
long tooth. Pygidium deeply sulcate in both sexes, in the ¢ exposed and subvertical. Fifth ventral 
segment broadly emarginate in the ¢. 
Length 24-3, breadth 12-14 millim. (¢ 2.) 
flab. Panama, Volcan de Chiriqui, Caldera (Champion). 
Hight specimens, varying a good deal in colour, some of them being almost entirely 
ferruginous, the legs included. The chief characters of A. sulcipygus are the sulcate 
and exposed pygidium in the male, the very deeply striate, somewhat gibbous elytra, 
the sparse pubescence, and the large and prominent eyes. It belongs to the subgenus 
Paranthonomus, Dietz, but the pygidium is more narrowly sulcate than in the North- 
American JA. profundus, Lec. 
A. ocularis-group. 
39. Anthonomus ocularis, sp. n. 
Subovate, piceous, the antenne (the club excepted) and legs ferruginous, the anterior femora and tibie partly 
infuscate ; sparsely clothed with yellowish-grey pubescence, which is condensed along the middle of the 
prothorax, the vestiture of the scutellum and under surface whitish. Head rugulose, the eyes large, 
somewhat coarsely facetted, and rather narrowly separated; rostrum about as long as the head and 
prothorax, moderately curved, seriate-punctate, smoother at the tip, the antenne inserted at two-fifths 
from the apex, joint 1 of the funiculus nearly as long as 2-4 united. Prothorax transverse, rounded at 
the sides, much narrowed and feebly constricted in front, densely, rugulosely punctate. Elytra much 
wider than the prothorax, gibbous, comparatively short, transversely depressed below the base, the 
humeri swollen and prominent; deeply punctate-striate, the interstices strongly convex and minutely 
punctate. Legs rather stout, elongate, the anterior pair especially ; femora each with an acute tooth, 
the anterior pair with a minute tooth exterior to the other ; anterior and intermediate tibie sinuate on 
their inner edge; tarsal claws with a long tooth. 
Length 22, breadth 13 millim. (d.)
