tales, Nicaragua, and Bugaba and David, Panama. In the present 

 species the elytra instead of being entirely deep violaceous are viola- 

 ceous with the basal third pale yellow. Also in the structure of the 

 male antennae the third and fourth joints are a little differently formed, 

 with a smaller round incision near the apical and basal ends of the 

 joints. Otherwise the two species bear a strong resemblance to each 

 other in spite of the widely separated regions in which they were 

 collected. Like Phyllecthrus , both species have only ten joints in the 

 male antennae. John A, Wilcox unearthed the specimens in the U.S. 

 National Museum collection and has generously handed them over to 

 me to describe.

 Deuterobrotica atlanta (Bechyne). — Bechyne, Ent. Arb. Mus. G. Frey, vol. 9, p. 

 596, 1958. 



About 5 mm. in length, oblong oval, shining, the elytra rather 

 coarsely punctate, antennae in the male with the terminal joints en- 

 larged and the middle tibiae excised near the apex. Head and pro- 

 thorax tan colored, head with a short dark piceous mark on either side of 

 the tan-colored occiput, elytra piceous with pale margins and suture 

 and a short incm'ving pale vitta on each elytron, body beneath and 

 legs except coxae black. 



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

 occiput rounded, frontal tubercles swollen, a slight depression over 

 them, a very short carina and a rather long lower front, pale except for 

 two piceous marks at the base of the occiput. Antennae in male with 

 the last three joints somewhat enlarged, thhd joint shorter than fourth, 

 entirely dark. Prothorax nearly rectangular, the explanate margin 

 visible from above entire length; very shiny with the transverse sulcus 

 shallow and not conspicuous except at the ends. Scutellum pale. 

 Elytra piceous, the margin and suture pale yellow and a short in- 

 curving pale vitta extending down from the intrahumeral sulcus and 

 not reaching the middle of the elytron. Body beneath and legs ex- 

 cept coxae dark. Coxal cavities open, claws appendiculate, middle 

 tibiae of the male with a small notch. Length 5.5 mm. 



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

 collected at Nova Teutonia, St. Catarina, Brazil, Nov. 5, 1950, F. 

 Plaumann collector. 



Remarks: Bechyne has described the genus Deuterobrotica as 

 having the terminal joints of the antennae in the male enlarged and 

 the pronotum with seta-bearing punctures on the side. He did not 

 note the excised middle tibiae in the male.
