NEOBROTICA AND RELATED GENERA — BLAKE 285 



Remarks : In the BMNH there are four specimens from Guatemala 

 besides the type, and these have variable elytral markings in which 

 the vittae are more or less interrupted. One of the specimens with 

 unbroken vittae bears the label Capetillo, Guatemala, collected by 

 Champion, and in the Bowditch collection is another from Capetillo 

 in which the median vitta is broken. In a later publication Jacoby 

 adds the locality Corozal, Colombia, for the species, but I have been 

 unable to find the specimen either in the British Museum or the Bow- 

 ditch collection. In the latter there are two specimens from South 

 America under this species, one labelled Venezuela, the other Caracas, 

 and in the U.S. National Museum is a specimen from Turmero, Vene- 

 zuela, collected in November 1931 by MartoreU. The only male 

 specimen is the one from Caracas, and whether these South American 

 specimens are the same as the ones from Guatemala is at present 

 impossible to say. 



As Jacoby notes, the markings of this species bear a strong re- 

 semblance to those of Diabrotica nigrolineata Jacoby.

Neobrotica linigera Jacoby, in Godman and Salvin, Biologia Centrali-Americana, 

 Coleoptera, vol. 6, pt. 1, p. 574, 1887. 



About 6.5 mm. in length, elongate oblong oval, shining, the elytra 

 with traces of costae and the intervals strongly and semistriately 

 punctate, pale yeUow with a piceous head and the marks on the elytra 

 having a bluish lustre, a subsutm-al vitta extending one-third the way 

 down, another from the humerus of equal length and two short vittate 

 marks below the middle, one on the side at the apical curve, and the 

 other near the suture, and in some specimens the pale yellow of the 

 elytra across the middle becoming a deeper yellow band, legs and 

 body beneath pale yeUow except the dark breast. 



Head with interocular space approximately half width of head, 

 frontal tubercles distinctly marked and a deep median depression over 

 them, the occiput finely punctate, a narrow carina running down lower 

 front, shining piceous with the mouthparts usually paler. Antennae 

 pale yellowish brown. Prothorax a little wider than long, with curved 

 sides and a transverse sulcus, finely punctate, shining, pale yellow. 

 ScuteUum pale. Elytra shining, with traces of costae especially 

 marked near base, having the intervals geminate striate punctate; 

 pale yellow with dark markings having a bluish lustre and consisting 

 of a long vittate mark from the humerus down the side curving slightly 

 inwards, in one specimen in the British Museum this inward curving 

 fascia almost joined with a subsutm-al vitta of the same length; below 

 the middle a vittate mark at apical curve and another often with a
