NOTES ON DIABROTICA AND DESCRIPTIONS OF NEW 



SPECIES. 



BY FRED. C. BOWDITCH, BROOKLINE, MASS. 



During the last two summers I have made the following notes on Mr. 

 Baly's paper. (Baly's Sec. i Trans. Ent. Soc, 1890.) 



Among the species labelled Lacordairei Kirsch, in the ist Jacoby collec- 

 tion I separate three examples as the \.x\\^fraterna Baly, described from 

 Guatemala ; the form is long, narrow and parallel, and in the ^ the 

 fourth joint of the antennae is as long as the first three joints ; some of the 

 forms classed by Jacoby as Lacordatrei, especially those collected by 

 Champion, have a black anal segment, which would seem to throw them • 

 out of this species. Mr. Baly, p. 7, speaks of the entirely black legs of 

 Lacordairei ; the Central American forms in the Jacoby collection have 

 base of femora pallid. 



Sanguinicollis Jac, Cist. Ent., II, p. 524, the type of which is in my 

 collection, I place near rugulipennis Baly. 



On page 25 Mr. Baly, speaking oi atoniaria Jac , says "the antennae 

 nearly equal to the body in length." Mr. Jacoby, in his description, P. 

 Z. S., 1889, p. 284, says "the antennas about half the length of the body." 

 My example from the Jacoby collection has the antennae missing, another 

 specimen from Venez (Caracas ?) seems to be a $ , the antennae are half 

 as long as the body. 



D. pauperata Baly, p. 27. The typical form has two discoidal black 

 spots, the first about the middle and the other about 1.5 mm. behind. 

 Specimens occur where the two spots are joined, forming a short discoidal 

 stripe, this form also having the humeral vitta whole, thus producing a 

 form resembling atrilineata Baly and its allies ; other specimens have the 

 discoidal spots entirely absent ; in both these last forms the sutural spot 

 is only a piceous line ; all the 16 examples in my collection come from 

 Bahia, Brazil, which is the typical locality for the species. 



On page 38 D. fulvofasciaia Jac. is given by Baly as a synonym of 

 tumidico?inis Er., the description of the former given by Jac, P. Z. S., 

 1889, p. 281, speaking of the ({ antennae, "the second and third joints 

 very short ar.d equal, the Ji/th to the fiinih Joints greatly dilated and 

 thickened," and the habitat Caracas. Baly, on pages 38-39, speaking of 

 tumidicontiis Er., says of the ^ antennae, "the 2nd joint very short, the 

 3rd nearly one-half longer, the 4th longer than the preceding two united,
