rounded at humeral angles, nearly parallel to behind middle, where 

 they are slightly wider, then arcuately attenuate to the tips, which 

 are separately narrowly rounded; lateral margins coarsely serrate 

 to middle, the teeth short, and widely separated posteriorly ; humeri 

 rather prominent ; base feebly angularly lobed ; disk without longi- 

 tudinal costa, but with an obsolete longitudinal costa along lateral 

 margin, extending from the humeri to post-median green fascia, 

 with a deep basal depression, and a more obsolete one at humeri and 

 on green ante-median fascia ; surface coarsely and densely punctate ; 

 intervals coarsely and densely granulose. Abdomen beneath 

 coarsely punctate, with the posterior and anterior margins of the 

 segments smooth, the intervals finely and densely granulose, more 

 shining than above, and the sides of the segments with smooth obso- 

 lete nodules; first segment not impressed at middle; last segment 

 with the lateral margins entire, with an obsolete submarginal ridge, 

 and the apex subtruncate. Prosternum with an obsolete lobe in 

 front; surface rather coarsely and densely punctate; prosternal 

 process flat, triangularly expanded behind the coxal cavities, and 

 with a very short obtuse tooth at apex. Femora robust; anterior 

 pair Avith a sharp acute tooth on the outer edge, closer to the apex 

 than base, and not serrate on the exterior margin. Anterior tibiae 

 feebly arcuate, flattened on the inner surface, and without any dila- 

 tations; middle and posterior pairs straight and subcylindrical. 



Length, 4.25 mm. ; width, 2 mm. 



This species was originally described from Key West, Florida, 

 by Schaeffer from a female specimen. Two males from Cuba in the 

 United States National Museum have been examined, one collected 

 at Cayamas, June 23, by E. A. Schwarz, and the other received from 

 H. F. Wickham and simply labeled Cuba. There is also a specimen 

 in the collection of S. C. Bruner, collected at Camaquey, Cuba, July 

 20, 1923, by J. Acuna. 



Mr. Schaeffer has kindly compared the Cuban specimen with his 

 type in the Brooklyn Museum and writes that it only differs from 

 the type in having the head more metallic green above and the 

 abdominal segments metallic green at the sides. The type being a 

 female, and the specimen from Cuba a male, would account for this 

 slight color difference. 



CHRYSOBOTHRIS SEXFASCIATA, var. JAMAICENSIS, new variety 



Female. — This variety differs from the typical species by the head 

 being entirely purpureous, with only a slight aeneous tinge, sides of 

 the pronotum more parallel and not as arcuately rounded, and the 

 lateral margins more rounded and not as sharply defined; elytra 

 not as densely nor deejDly punctate, the punctures becoming obsolete 

 toward the apex, the green spots more bluish, and the antemedian
