14 RHYNCHOPHORA. 
from many of the above localities we have received only one example, but Mr. Cham- 
pion procured a fair series at San Gerdnimo. ‘The only important sexual distinctions 
are to be found in the front legs: in the male the front femora are bidentate, the tooth 
placed on the middle being long and slender, much longer than the other nearer the apex, 
and the tibie are slender and possess a single mucro at the apex ; in the female the femora 
are also bidentate, the tooth on the middle being, however, quite short, shorter than the 
other, and the tibie are stouter and bimucronate at the apex. There is some variation in 
size, the specimens from Panama and Nicaragua being smaller than most of the others ; 
the peculiar spot on the wing-cases is also rather larger in some specimens, but the 
difference in this respect is not great. We figure the female example from Nicaragua. 
31. Attelabus fenestratus, sp.n. (Tab. I. fig. 12, 2.) 
Rufus ; capite prothoraceque eneo-micantibus ; abdomine, pedibus quatuor posterioribus femoribus anterioribus 
ad basin pallide flavis, tibiis tarsisque anterioribus rufo-testaceis ; elytris plagis duabus magnis, eburnaceis 
ornatis. 
Long. 4 millim. 
Hab. Panama, Bugaba 1000 feet (Champion). 
Closely allied to A. dinotatus, but easily distinguished by the colour-characters, and 
the remarkably conspicuous ivory-like marks on the middle of the elytra; it is also a 
shorter insect. 
Described from a single female. The front femora are bidentate as in A. binotatus, 
but the outer tooth is strongly sinuous externally. 
82. Attelabus championi, sp. n. 
Sat elongatus, rufus ; abdomine pedibusque quatuor posterioribus minus saturatis, femoribus anterioribus ad 
basin flavis; elytris fortiter punctatis, guttis duabus testaceis, pellucidis, rotundatis ornatis. 
Long. 5 millim. 
Hab. Panama, Bugaba (Champion). 
Of this species also we have received only one female: it is very similar to the more 
elongate examples of A. binotatus, but is no doubt quite distinct; the antennal club is 
elongate ; the front legs are dark sanguineous-red, the tibiae being concolorous with the 
femora, and these last having the slender basal portion clear yellow. The thorax is 
very polished and has a brassy tinge; the elytra are long and slender, their sculpture 
very coarse and irregular, but much less deep than in A. binotatus ; the apical tooth 
of the front femur is longer and more’slender than it is in A. binotatus. 
33. Attelabus cruralis, sp.n. (Tab. I. fig. 13, 3.) 
Elongatus, piceus; antennis pedibusque elongatis; elytris grosse punctatis, medio guttula testacea pellucida 
ornatis. 
Long. 7-8 millim. 
Hab. Mexico, 'Toxpam (Sal/é); GuaTEMALA, Las Mercedes, Cerro Zunil, Purula 
(Champion); Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).
