deeply, arcuately emarginate at apex, with the angles narrowly rounded, and 

 with a strongly elevated, serrate, submarginal ridge, lateral margins not serrate ; 

 eighth tergite coarsely, sparsely punctate, densely granulose, with dorsal margin 

 broadly subtruncate. Prosternum sparsely punctate, transversely rugose, 

 sparsely clothed with moderately long, semierect hairs ; anterior margin with 

 a very narrow, inconspicuous, median lobe. Anterior femur with a short, 

 obtusely rounded tooth, which is coarsely dentate on outer margin, and with a 

 small, triangular tooth behind the larger tooth. Anterior tibia strongly arcuate, 

 suddenly bent at middle ; middle tibia strongly arcuate ; posterior tibia straight. 

 Length 14 mm., width 6.5 mm. 



Redescribed from a male from Miami Beach, Fla., in the United 

 States Xational Museum. 



Female. — Differing from the male in having the head piceous, with distinct 

 greenish and purplish tinges, and a transverse chevron on the occiput, the 

 antenna brownish cupreous, the last visible abdominal sternite shallowly, 

 arcuately emarginate at apex, with the exterior angles acute and strongly pro- 

 duced, and strongly sinuate at middle of emargination, the eighth abdominal 

 tergite more coarsely, confiuently punctate, and broadly rounded at apex, the 

 anterior femur without a small triangular tooth, and the anterior and middle 

 tibiae less arcuate. 



Type locality. — Of tranquebarica* "Tranquebariae" ; present loca- 

 tion of type unknown to writer. Of frateriw, Puerto Rico, and of 

 rugosa, locality unknown: types in the Zoological Museum, Uni- 

 versity of Helsingfors. Of denticulata, Guadeloupe: type in collec- 

 tion of Rene Oberthur. Of dentkollis* Bogota, Colombia; type in 

 Reiche collection (supposed to be in the Natural History Museum, 

 Geneva, Switzerland). 



DISTEIBUTION 



From material examined : 



Florida: Key "West. April 1887 (Hubbard and Schwarz). Miami, April to June, 

 reared; Hobe Sound, May 16, 1916 (T. E. Snyder). Paradise Key (C. A. 

 Mosier) . West Lake, near Cape Sable, February 25. 



West Indies : Guadeloupe, St. Thomas, Grenada, Puerto Pico, Bahamas, Haiti, 

 and Dominican Republic. 



It has been recorded in the literature from Elliott Key. along 

 Biscayne Bay. and Key Biscayne. Fla. Chamberlin (1926) and 

 Obenberger (1934) record it from Cuba, but the writer has not seen 

 any specimens of this species from that island, all the specimens 

 labeled tranquebarica being twrdda. 



Hosts. — This species has been reared from Australian-pine (Casu- 

 arina equiseti folia Foster) and red mangrove (Rhizophora mangle 

 Linnaeus) in Florida by T. E. Snyder. Chamberlin (1926) records 

 it from buttonwood (C ono carpus erecta Linnaeus), but this host- 

 plant record should be verified. Russo collected the adults on the 

 trunk of "canafistola (Cassia fistula)'' in the Dominican Republic. 

 The natural host plant seems to be the red mangrove, as adults were 

 collected in Florida before the "Australian pine" was introduced 

 into that region. 



The sculpture is rather uniform, but the color of the foveae on the 

 elytra varies from lilacinous through reddish cupreous to viridian. 

 Some of the specimens examined have more or less distinct, smooth, 

 flat callosities at the sides of the abdominal sternites. Usually the 

 median lobe on the prosternum is slightly indicated, but occasionally 

 specimens are found with the anterior margin of the prosternum 

 truncate, without any indications of a median lobe. The length is 

 from 12 to 16.5 mm.
