76 PROCEEDINGS OF THE NATIONAL MUSEUM vol. los 



Head smooth and shining, with a shallow depression over the well- 

 marked frontal tubercles, space between antennal sockets slightly 

 produced in a short carina down front; labrum wide, jaws large, lower 

 front deep reddish brown, upper part of head dark with a violaceous 

 lustre. Antennae entirely pale, not extending to middle of elytra, 3d 

 joint shorter than 4th, joints 3-9 subequai, the two distal joints in the 

 male enlarged and somewhat distorted. Prothorax a little wider than 

 long, with slightly curved sides and oblique basal angles, moderately 

 convex, the disk without depressions, shiny yellowish. Scutellum 

 pale. Elytra shiny, pale with dark violaceous spot covering humerus 

 and extending almost to scutellum, another larger dark spot below 

 middle extending from the margin nearly to the suture, but not reach- 

 ing apex. Body beneath pale except the last two ventral segments, 

 which are deep violaceous. Femora and tibiae dark, the tarsi reddish 

 brown. Middle tibiae of male with notch near apex, no spurs dis- 

 cernible on tibiae. Claws appendiculate. Length 5.5 mm.; width 2.4 

 mm. 



Type: Perhaps in Gundlach collection in Havana, Cuba. Collected 

 in Cuba. 



Other localities: Cuba: Havana, Baker; Taco Taco, S. C. 

 Bruner, A. Acuna, C. H. Ballou. 



Remarks: I know of no other galerucid beetle that has the enlarged 

 hind femora, notched middle tibiae, and antennal enlargement in the 

 male. Leptoxena eximia Baly from the Andaman Islands, also a 

 galerucid beetle, has similar enlargement of the hind femora and 

 dilated antennal joints in the three distal joints, but not the notched 

 middle tibia. It is an entirely different looking beetle and in no way 

 related to the present one. 



IceloceraSy new genus 



Elongate oblong oval, glabrous, confusedly punctate, antennae 

 filiform, not enlarged in male, the 3d joint sometimes subequai to 2d, 

 sometimes twice as long; prothorax subquadi-ate, wider than long, 

 with slightly curved sides; a semicircular depression in lower half. 

 Elytra little widened apicaily, epipleura vanishing at apical curve; 

 anterior coxal cavities open; anterior front tibiae in male swollen and 

 first tarsal joint short and wide Avith undersurface having tympanum- 

 like covering; middle tibiae of male notched near apex; middle and 

 hind tibiae with small spur; first tarsal joint of posterior legs long, 

 nearly equalling the rest of joints together; claws appendiculate. 



Type of genus: Diabrotica sexplagiata Jacoby. 



The type of the genus Neobrotica, as has been so designated by 

 Weise, is A^. variabilis Jacoby. The several species that have been 

 confused under the name of N. sexplagiata (Jacoby) bear little
