COPTURUS. 75 
truncate at the tip, the sutural angle rounded, the sutural region broadly depressed ; finely punctate- 
striate, the interstices flat on the disc. Meso- and metasternum flattened between the middle coxe. 
Legs rather short; anterior femora bidentate, intermediate and posterior femora with a blunt lamelliform 
prominence exterior to the other tooth, both pairs sharply carinate externally ; posterior tibize com- 
paratively broad. 
Length 53-67, breadth 2,9,-3,1, millim. 
Hab. Nicaracua, Chontales (Belt). 
Two specimens. The elytral markings in this species are fulvous, and in part edged 
with white, as in Zygops amenula, an insect also occurring at Chontales. The bidentate 
femora and the relatively long fourth joint of the funiculus are also characteristic. 
C. fulvomaculatus belongs to the section Eucopturus, Heller. 
12. Copturus sericeus, sp. n. (Tab. V. fig. 12.) 
Elliptic, robust, opaque, piceous or nigro-piceous, the rostrum, and sometimes the legs in part, rufescent, the 
antenne ferruginous; the vestiture close and very fine: the head with a line around the eyes, and the 
prothorax with three vitte (sometimes connected in front, the central one enclosing a short, bare, median 
line), ochreous; the elytra with a broad transverse space at the base and another at the middle, connected 
along the suture, a spot at the sides at about one-third from the apex, the apical portion of the suture, 
and various undulate interrupted fasciz or scattered spots, sordid ochreous or flavo-cinereous, the rest of 
tbe vestiture fuscous ; the under surface with coarser whitish scales, the fifth ventral segment with a bare 
spot. Eyes extremely large, very narrowly separated. Rostrum rugulose and carinate at the base, and 
sparsely, minutely punctate thence to the tip. Joint 2 of the funiculus as long as 3-5 united, 3 and 4 
subequal in length. Prothorax transverse, narrowing from the base, strongly constricted.in front; 
densely, minutely punctate, rugulose on each side of the smooth, cariniform, median line. Elytra some- 
what oval, blunt at the tip, depressed along the suture anteriorly ; finely punctate-striate, the interstices 
feebly convex. Meso- and metasternum flattened between the middle coxe, the mesosternum slightly 
swollen on each side. Legs short and stout; femora broad, sharply unidentate beneath, the posterior 
pair carinate externally and strongly compressed. 
Length 53-53, breadth 23-22 millim. 
Hab. Panama, Bugaba (Champion). 
Three specimens, two of them somewhat immature. Distinguishable by the fine 
silky vestiture, the comparatively smooth prothorax, the finely striate elytra, and the 
broad femora. C. sericeus seems to belong to the subgenus Lucopturus of Heller; the 
femora are nearly as broad as in Cyphocopturus tristis. 
13. Copturus maculosus, sp. n. (Tab. V. fig. 13.) 
Very like C. sericeus, but with the vestiture a little coarser, the median vitta of the prothorax interrupted ; 
the prothorax closely, uniformly punctate, and also carinate; the elytra a little less rounded at the sides, 
the apices more abruptly truncate, the strie distinctly punctate, the sutural region less depressed; the 
meso- and metasternum slightly depressed between the middle cox ; the fifth ventral segment without 
a bare spot in the middle; the legs not so stout, the femora narrower ; the eyes subcontiguous. 
Length 42-44, breadth 23-22 millim. 
Hab. Payama, Volcan de Chiriqui, Bugaba (Champion). 
Two specimens, easily separable from C. sericeus by the characters given, the
