460 BRUCHIDES. 
as long as the fourth and more slender, the fifth to the tenth each about as long as broad. 
Eyes very deeply emarginate, little separated; vertex carinate. Thorax very narrow in 
front ; its surface uneven in consequence of a transverse depression in front of the middle, 
and a slight convexity of the basal portion, very densely and indistinctly, though not very 
finely, sculptured ; very sparsely clothed on each side with white. Scutellum minute, 
white. Elytra finely but deeply striate just before the middle, with an irregular, very 
faint, milky-white band, and in front of this a depression. Pygidium only mode- 
rately large, very finely sculptured, and bearing a white, very delicate, clothing, not 
concealing the ground-colour. Front and middle tarsi and apices of the tibiz yellow; 
hind tarsi yellow, with the basal joint black, except at its extremity. Femora moderately 
dilated ; tibiee arcuate at the base, unarmed at the extremity. 
This is a very distinct species, but is undoubtedly allied to the following, B. cyani- 
pennis. Both species have a similarity in form to the European B. canus, but the apical 
ventral rings are considerably shorter in the New-World species. Only three examples 
were found of B. ptinoides. 
45. Bruchus cyanipennis. (Tab. XXVI. fig. 9.) 
Niger, tenuiter griseo-pubescens ; elytris cyaneis, tarsis anterioribus interdum fuscis ; antennis sat elongatis, intus 
subserratis ; prothorace conico, dense sculpturato, opaco ; elytris minus subtiliter striatis ; femoribus posteri- 
oribus dente sat elongato denticulisque quinque minutis armatis. 
Long. 24-24 millim. (capite deflexo). 
Hab. Guatemata, Tamahu, San Juan, and La Tinta in Vera Paz (Champion); Panama, 
Volcan de Chiriqui below 4000 feet (Champion). 
This species has greatly the aspect of the European B. canus, Germ., which, however, 
has unarmed tibie. It is closely allied to B. ptinoides, but differs not only by the even 
surface and the blue elytra, but also by the fact that the hind tibie are armed with a 
short spur. I presume that the front tarsi being obscurely flavescent is a mark of the 
male sex. 
Eight examples were brought back from Guatemala and two from the Volcan de 
Chiriqui; the latter have the front and middle feet paler than they are in the males of 
the examples from Guatemala. 
46. Bruchus serraticulus. 
Angustulus, niger, tenuiter albido-vestitus, tibiis tarsisque anterioribus flavis ; antennis gracilibus, intus subser- 
ratis; prothorace conico, densissime sculpturato, opaco; femoribus posterioribus denticulis minutis 
quatuor armatis. 
Long. 13 millim. (capite deflexo), 
Hab. Muxico, Guanajuato (Sallé). 
The antenne in this species are formed much as in B. ptinoides (but are not so wide), 
the second joint being very small in proportion to the third; the eyes are very promi-
