10 THE CANADIAN ENTOMOLOGIST. 



\.\\^ yth and f olio whig two ]o\Vi\% in the $ thickened," and the habitat 

 Peru and BoHvia. 



The differences given in the above descriptions are even more notice- 

 able in the specimens themselves ; the two forms are plainly distinct, and 

 should not be united. I have one ^ of each form from the type localities. 



D. tibialis Baly, p. 79. This name being previously used by Jacoby 

 in the Biologia, p. 512, should be changed to confusus. 



D. variolosa Jac. (type in my collection) comes near marginata 

 Sturm. 



In identifying species of this genus, it should be borne in mind that 

 the antennae of the ^ 's are usually the longer, and the third joint in the 

 (^ is relatively shorter than the same joint in the 9 . The foveation of 

 the thorax seems to me, in some instances at least, to be possibly a matter 

 of sex. Tins, however, is more a suggestion for future research than a 

 definite opinion. 



The specimens sent me by Messrs. Staudinger and Bang-Haas as 

 cotypes Qi\ D. angustofasciata Jac. in litt., belong to Liiperodes. 



D. suffusa Baly is not mentioned in Mr. Baly's paper. If it has been 

 sunk as a synonym I have overlooked it. The Jacoby collection had it 

 marked as a distinct species. I place it near rtigulipe?mis Baly. 



D. ha/meli, nov. sp. 



Black, base, and joints nine and ten of antennae, thorax, femora and 

 middle of first three abdominal segments yellow, elytra almost smooth, 

 slightly plicate, with four white spots on each side placed 2-1-1. Length 

 7 mm. 



Type collected by Dr. Hahnel, Amazons (Staudinger). 



Form stout, head bUck, clypeal ridge not well defined, antennae stout, 

 more than half the length of the body, joint 2 short, 3 barely one-half 

 longer, 4 much longer than the two preceding united, joints 1-3 flavous, 

 tinged with piceous above, 9-10 and base of 11 flavous, thorax flavous, 

 convex, shining, broader than long, a i^w fine punctures at the sides, 

 lightly trifoveate, scutel dark i)iceous, elytra shining black, very finely 

 punctate, a round while spot back of the base, near the suture, a smaller 

 one near the margin back of the shoulder, a small transverse spot back of 

 the middle and a round spot at the apex, equidistant from the margin and 

 suture ; the inflexed edge of the elytra, behind the shoulder, is faintly 

 piceous, body beneath black, excepting the thorax, the anterior breast and
