male alone in this genus shows the thickening of the antennal joints. 

 All three species occur in the same region, are congeneric and very 

 closely related. Undoubtedly the males of both latifrons and bechynei 

 have thickened antennal joints and the middle tibiae are excised near 

 the apex. 



Deuterobrotica latifrons (Bechyne) 



Figure 26 

 Neobrotica latifrons Bechyne, Ent. Arb. Mus. G. Frey, vol. 9, no. 2, p. 600, 1958. 



About 6 mm. in length, elongate oblong oval, shiny, faintly aluta- 

 ceous, sparsely but distinctly punctate, pale yellow, the prothorax 

 with a broad anterior piceous spot on each side, each elytron with two 

 piceous vittae not reaching the apex, one lateral, the other median. 

 Antennae dark brown, tibiae and tarsi dark. 



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

 occiput smoothly rounded, nearly impunctate, tubercles distinct, 

 carina broad and rather flat, lower front short. Antennae long, 

 slender, deep reddish brown, third joint shorter than fom-th. Pro- 

 thorax about one-third wider than long, with the lateral explanate 

 margin visible from above all the way, the pores of this margin of which 

 Dr. Bechyne writes not visible in the British Museum specimen al- 

 though seen in the type in the Frey Museum; surface shining, finely 

 punctate, a broad shallow transverse sulcus, pale yellow with a broad 

 piceous area extending from the anterior margin to the sulcus and a 

 little farther along the side but not reaching the middle on either side. 

 Scutellum pale. Elytra with three faint costae on outer haK of each 

 elytron, finely and rather sparsely punctate, pale yellow with a median 

 piceous vitta, wider near the base, and a lateral vitta from the humerus 

 to apical ciu"ve, wider at the apical curve. Body beneath pale, shiny, 

 not pubescent, anterior coxal cavities open, femora pale, tibiae and 

 tarsi dark, claws appendiculate. Length 5.7-6 mm.; width 2.8 mm. 



Type, female, in G. Frey Museum, Tutzing bei Miinchen, Germany, 

 from Santa Catarina, BrazU. A second specimen, also a female, in the 

 British Museum, from the same locality is a better specimen than the 

 type which appears to be immature with the elytra and abdomen 

 shrunken. In the British Museum specimen the elytra are clearly 

 but sparsely punctate. 



Remarks: The British Museum specimen bears the label "9? am- 

 plicornis." It is not D. amplicornis but a closely related species with 

 slightly different pronotal markings, in that the dark areas do not 

 extend to the base, and the elytral vittae are not joined at the apex. 

 Amplicornis is also more coarsely punctate. I believe that the male 

 wiU have excised middle tibiae and enlarged antennal segments.
