GALERUCINE BEETLES — BLAKE 89 



entirely pale, shining, impunctate. ScuteUum pale. Elytra a little 

 wider towards apex, with wide explanate margin, a well-marked 

 intrahumeral sulcus curving towards suture; surface obsoletely 

 punctate, shining, pale with a violaceous brown sutural mark that 

 is wide about suture, ciu-ving down to a narrow stretch in middle 

 of elytra and again widening beyond the middle to cover all but 

 margin in apical third. Epipleura vanishing before apical curve. 

 Body beneath and legs entirely pale. Middle tibiae in male notched, 

 a fine spine on tibiae; claws appendiculate. Length 6 mm.; width 

 2.4 mm. 



Type : In British Museum (Natural History) , from Ruatan Island, 

 Honduras. 



Other localities: Honduras: Puerta Castilla, Jos. Bequaert, 

 April (MCZ); "Roatan Id.," F. J. Dyer, Mar. 28, 29, 1916. 



Remarks: In the short third antennal joint this species resembles 

 Luperosoma, but there is no enlargement of the antennal joints. 



Iceloceras flavocyaneutn, new species 



Figure 5,a 



Between 4 and 5 mm. in length, elongate oblong oval, shining, 

 nearly impunctate, the elytra very finely punctate, yellow with 

 posterior part of elj^tra violaceous; antennae pale with the last five 

 joints a little darker; middle tibiae notched in male. 



Head with interocular space half its width, smooth, shining, im- 

 punctate, pale yellow; frontal tubercles not very distinct, a median 

 line from between antennal sockets. Antennae with 2d and 3d joints 

 short, 4-11 long and subequal, the five basal joints pale, the remainder 

 reddish brown. Prothorax a little wider than long with slightly 

 curved sides, shallowl}^ depressed in lower half, shining, impunctate, 

 pale yeUow. Scutellum pale. Elytra shining, very finely punctate, 

 pale yellow with a violaceous spot covering apical third, leaving margin 

 pale (in one specimen from Panama the suture also pale). Epipleura 

 vanishing before apical curve. Body beneath entirely pale, tibiae 

 with tiny terminal spine; claws appendiculate, middle tibiae notched 

 in male. Length 4-5.3 mm.; width 1.8 to 2.2 mm. 



Type: Male, USNM 63362, from Santa Lucretia, Tehuantepec, 

 Mexico, W. Al. Mann; one paratype in Museum of Comparative 

 Zoology. 



Other localities: Santa Lucretia, Vera Cruz, Mexico, F. Knab; 

 XX Plantation, Panama. 



Remarks: This species is closely related to /. ruatanae (Jacoby) 

 with the same short 2d and 3d antennal joints, and is intermediate in 

 the matter of generic placing between Iceloceras and Luperosoma.
