GALERUCINE BEETLES — BLAKE 249 



Remarks: The long slender antennae with the short compressed 

 thu-d joint in the male, the front of the head that is slightly bulging 

 and without any spine, and the rather short prothorax differentiate 

 this genus from the Central American genus Platymorpha, in which 

 the antennae are stouter, there is a spine on the lower front of the 

 face, and the prothorax is longer.

 Romanita vittata Bechyne, Ark. Zool., vol. 11, p. 137, 1958. 



About 4.5 mm. in length, elongate oblong oval, the antennae missing, 

 the prothorax smooth and without any transverse depression, elytra 

 with a slight depression below basal callosity and another below the 

 middle, finely punctate with a tendency towards being striate; pale 

 yellow brown with the occiput of the head dark, three dark pronotal 

 vittae, the middle one the widest, and a wide vitta on each elytron 

 covering more than half of each, breast brownish. 



Head with the interocular space about half width of head, occiput 

 rounded, frontal tubercles distinct, carina short ending in a slightly 

 swollen ridge below the antennal sockets; pale yellow brown with the 

 mouthparts brownish. Antennae missing, but said by Bechyne to be 

 like those of R. amazonica. Prothorax wider than long with slightly 

 curved sides and without any transverse sulcus visible to me although 

 Bechyne stated it was "feebly impressed"; shiny pale yellow with a 

 wide median vitta and a narrower one on each side. Scutellum dark. 

 Eyltra narrow, elongate, with a slight basal callosity and a depression 

 below, and also another transverse impression below the middle, 

 punctation fine, tending to be striate; pale yellow brown with a wide 

 piceous vitta on each elytron beginning at the humerus and widening 

 gradually towards apex but not extending to the suture, the apex dark, 

 lateral margin pale, epipleura vanishing at apical curve. Body 

 beneath pale with the breast brownish, the femora pale with a dark 

 streak above, tibiae and tarsi brownish, a spine on hind tibiae, ? on 

 others, claws appendiculate. Length 4.5 mm.; width 2 mm. 



Type, female, in Naturhistoriska Riksmuseet, Stockholm, Sweden, 

 from S. Gabriel, Roman expedition, collected on December 26. 



Remarks : This female specimen with no antennae and without any 

 discernible depression across the pronotum is without any characters 

 by which it can be definitely placed in the genus Romanita.
