base, the sides and half way down the suture, a small dark spot near 

 the apex common to both elytra and a still smaller spot on each 

 elytron near it. 



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

 occiput with fine punctures, a depression over the frontal tubercles, 

 and a short and somewhat depressed carina down the lower front 

 with punctures on either side. Antennae with the three basal and 

 three terminal joints pale, the rest dark. Pro thorax not twice as 

 broad as long with the sides slightly rounded, a well defined transverse 

 sulcus across disc; surface shining, very finely and sparsely punctate, 

 pale. Scutellum pale. Elytra widened behind, shining, not aluta- 

 ceous, distinctly costate, the costae not much elevated but broad and 

 smooth and impunctate, between them rather fine geminate striate 

 punctures, coarser on the sides; pale reddish brown with dark piceous 

 markings along the side, base, and narrowly down the suture to the 

 middle; a small spot common to both elytra before the apex and near 

 it a still smaller spot on each elytron. Body beneath with the breast 

 dark, the femora pale, tibiae and tarsi dark brown. Length 6.8 mm.; 

 width 3.5 mm. 



Type, female, BMNH, from Cordova, Mexico, collected by Salle; 

 only a single specimen known. 



Remarks: The costate elytra and dark markings along the side 

 differentiate this from other Central American species. The color 

 pattern is similar to several South American species, which have more 

 deeply costate elytra that are here treated in the genus Hystiopsis, a 

 genus that appears to be confined to South America.

Neobrotica punctatissima Jacoby, in Godman and Salvin, Biologia Centrali- 

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



About 6 mm. in length, broadly oblong oval, somewhat shiny, the 

 elytra very coarsely and irregularly geminate striate punctate, pale 

 yellow brown, the head deep reddish brown to the frontal tubercles, 

 antennae, legs and body beneath pale, elytra with metallic blue-gi'een 

 markings consisting of a circle in the basal part and a semicircle in 

 apical half. 



Head with interocular space fully one-half width of head, occiput 

 finely punctate, a median depression over the frontal tubercles, a well 

 developed carina down lower front, occiput deep brown to the frontal 

 tubercles, lower front pale, jaws tipped with brown. Antennae 

 entirely pale. Prothorax broad and with rounded sides, a deep 

 rounded depression on each side but not much evidence of a transverse
