NEOBROTICA AND RELATED GENERA BLAKE 305 



Remarks: This species is readily distinguished from others of sim- 

 ilar markings by its dull, coarsely punctate elytra. In this respect 

 it resembles A^. pluristicta Fall, but the latter species is much more 

 definitely costate. 



Neobrotica poecila, new species 



Figure 45 



About 5.5 mm. in length, elongate oblong oval, alutaceous, not 

 very shiny, the elytra rather densely but not coarsely punctate, and 

 with faint costae, pale yellow brown; the occiput, intermediate joints 

 of the antennae, tibiae and tarsi, and the middle of the breast brown; 

 the elytra with small piceous spots on the humerus, about the scutel- 

 lum, two in a line down the middle and two along the side of each 

 elytron. 



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

 smooth except for the fine punctures about the median depression 

 above the frontal tubercles, carina thin and not greatly elevated, 

 occiput dark, lower front pale. Antennae pale with joints five to 

 eight piceous. Prothorax not much wider than long, with the usual 

 transverse sulcus well marked, sides slightly curved, alutaceous, pale 

 yellow. Scutellum brownish. Elytra with traces of three or four 

 costae, distinctly but not coarsely punctate, alutaceous, not shiny, 

 pale with a small piceous spot on humerus, another surrounding the 

 scutellum, two in a line down the middle and two along the side of 

 each elytron. Body beneath pale with the middle of the breast 

 brownish; femora pale, tibiae and tarsi mostly deeper brown. Length 

 5.5 mm.; width 2.8 mm. 



Type, male, MCZ 30666, from "Brazil." 



Remarks: The elytral pattern is similar to many species of Neo- 

 brotica from Central America. There is one specimen without local- 

 ity label in the U.S. National Museum, a gift from the Bowditch 

 collection.

 Neobrotica dimidiaticornis Jacoby, Proc. Zool. Soc. London, p. 285, 1889. 



Between 5 and 7 mm. in length, elongate oblong oval, feebly shining, 

 alutaceous, pale yellow brown with darker markings on the vertex, 

 the intermediate joints of the antennae and spots or short vittate 

 markings on the elytra, undersurface and legs entirely pale. 



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

 tubercles swollen, a median depression above, occiput smooth, a 

 narrow carina down lower front; occiput more or less piceous and 

 mouthparts brownish. Antennae pale with the intermediate joints 

 usually darker, sometimes nearly piceous, or in one specimen only
