about equal in width; sides regularly arcuately rounded; anterior 

 margin broadly arcuately emarginate, without a median lobe; base 

 broadly arcuately emarginate on each side at elytral lobe, with the 

 median lobe broadly rounded, and truncate in front of scutellum; 

 posterior angles rather obtuse; surface evenly convex, and without 

 impressions, rather densely and regularly punctate, the punctures 

 ratlier deep, well separated, and becoming somewhat coarser toward 

 the sides; intervals finely and densely granulose. Scutellum vei-y 

 small, triangular, the sides equal in length, and the surface obsoletely 

 granulose. Elytra distinctly wider than pronotum at base; sides 

 broadly rounded at humeral angles, nearly parallel to apical third, 

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

 which are separately broadly rounded; lateral margins rather 

 strongly serrate to near the middle ; humeri not very prominent ; base 

 broadly arcuately lobed ; surface without costae, but each elytron with 

 a round deep basal impression, a shallow one at humerus, a long nar- 

 row one along lateral margin behind humeral angles, a large round 

 deeper impression in the ante-median green area, and a smaller one 

 in the post-median green fascia, densely and regularly punctate, the 

 punctures rather deep and well separated on the disk, but becoming- 

 obsolete in the humeral areas; intervals densely and rather coarsely 

 granulose. Abdomen beneath sparsely and coarsely punctate, the 

 punctures shallow, irregularly placed, and from each arises a short 

 inconspicuous cinereous hair: intervals obsoletely granulose; first 

 segment not impressed at middle ; last segment with the lateral mar- 

 gins entire, with an obsolete serrate submarginal ridge, and the apex 

 broadly subtruncate. Prostemum with a narrow declivous lobe in 

 front ; surface more deeply punctured than the abdomen ; prosternal 

 process flat, strongly expanded behind the coxal cavities, and with a 

 triangular tooth at apex; anterior coxal cavities separated by about 

 their own diameter. Femora robust; anterior pair with a large 

 acute tooth on the outer edge, closer to the apex than base, and finely 

 serrate on the exterior margin. Anterior tibiae feebly arcuate, 

 strongly flattened, without any dilatations, the middle and posterior 

 pairs straight and subcylindrical. 



Length, 6 mm.; width, 3 mm. 



Type Zoc«Z^^//.— Jamaica. 



Type. — British Museum. 



Described from a single female kindly loaned bv the British 

 Museum and labeled Jamaica, without a definite locality. 



It is closely allied to Chrysohothris Jepida Castelnau and Gory, 

 but can be easily distinguished from that species by the pronotum 

 htiving the sides arcuately rounded and not angulated anteriorly. 

 It is also related to G. luolcotti Fisher from Porto Rico, but in
