Type, female, BMNH; type of variety, female, Bowditch collection, 

 MCZ; both collected by Hoge in Jalapa, Mexico. 



Remarks: The two specimens from Jalapa, Mexico, one of which 

 Jacoby named a variety, are probably the same species. But Jacoby 

 in 1889 described briefly two specimens collected at Corozal, Vene- 

 zuela, that he stated agreed in every way with the Mexican specimens 

 except in the color of the legs and antennae, which were entkely pale in 

 the Venezuelan specimens. The writer has examined one of these 

 Venezuelan specimens that is in the Bowditch collection (]MCZ) and 

 believes it different and is describing it as a new species. Weise has se- 

 lected Neobrotica variabilis as the type of the genus.

Figure 9 



Neobrotica imitans Jacoby, in Godman and Salvia, Biologia Centrali-Americana, 

 Coleoptera, vol. 6, pt. 1, p. 573, 1887. 



Between 5.5 and 7 mm. in length, elongate oblong oval, shining, 

 faintly alutaceous; body pale yellow brown, the antennae and legs 

 entirely pale, the head, breast and spots on the elytra piceous. 



Head with the interocular space less than half width of the head, 

 shining piceous, the occiput with faint punctm'es and a median de- 

 pressed spot above the frontal tubercles, a short carina down lower 

 front. Antennae entu-ely pale. Prothorax not twice as wide as long, 

 with rounded sides and a transverse sulcus, very finely punctate, 

 faintly alutaceous, pale yellow brown. Scutellum deep brown. 

 Elytra widened in apical half, rather densely, coarsely and shallowly 

 punctate, the punctures tending to be striate, very faint traces of 

 costae; pale yellow brown with a long inwardly cur^dng black ^'itta 

 from humerus about one-fom-th the way down elytra; another vitta 

 from about scutellum down the sutm'e a short way, a triangular spot 

 near these in the middle and before the apex a median and a lateral 

 spot. Body beneath and legs pale with the breast dark. Length 

 5.5-7 mm.; width 2.7-3.5 mm. 



Type, male; one female paratype; both BMNH; one female para- 

 type, MCZ; all from Costa Rica, collected by Van Patten. 



Other localities: Coronado, Costa Rica, 1400 m., 1932, collected by 

 Nevermann. 



Remarks: The three specimens of the series collected in Costa Rica 

 by Van Patten are all very much alike. A specimen from the Baly 

 collection without a legible locality is in the British Museum. As 

 Jacoby writes, this species strongly resembles Diabrotica novemmaculata 

 Jacoby in its elytral pattern.
