PHELISTER. 
Phelister, Marseul, Monogr. in Ann. Soc. Ent. Fr. 1853, p. 462. 
Only about sixty species of Phelister have been noticed as yet by authors, but it is 
evident from the number of forms unnamed in collections that the genus is a large one. 
Some of the species assigned to it, viz. P. lunaticus and P. celebius, Mars., from the 
Eastern Archipelago, and P. impressifrons (Sol.), from Chili, have, as Herr Schmidt 
has noticed, an emarginate mesosternum, and these would, therefore, be better placed 
in Platysoma. The majority of the known forms are from the tropical and subtropical 
parts of America; some appear to be found under loose bark, others in dung, decaying 
vegetable matter, &c. 
1. Phelister godmani, sp.n. (Tab. V. fig. 1.) 
Ovalis, depressiusculus, supra fulgidus, subtus niger, nitidus ; fronte concava, sparse et grosse punctata, stria 
semicirculari antice interrupta; pronoto purpureo-aurato, circum punctato, stria haud interrupta ; elytris 
viridi-cyaneis, apice punctatis, striis dorsalibus 1 —4™ integris, 5" subintegra, suturali ultra medium abbre- 
viata; propygidio pygidioque punctatis; prosterno bistriato; mesosterno bisinuato, marginato, stria 
postice utrinque abbreviata. Long. 27 millim. 
Hab. Panama, Bugaba 1000 feet (Champion). 
One specimen. In its brilliant colouring this insect is similar to P. dives, Mars., 
from Rio Janeiro. P. dives is, however, a convex species, and has no fifth dorsal stria. 
P. riehli, Mars., from Cuba, is also closely allied to P. godmani, but the fifth and sutural 
striee are wanting in that species. 
2. Phelister eximius, sp.n. (Tab. V. fig. 3.) 
Breviter ovalis, parum convexus, supra viridi-cyaneus, subtus niger, nitidus ; fronte parce punctata, stria valida, 
integra, antice subarcuata; pronoto lateribus elevatis, utrinque punctato ; elytris postice punctatis, striis 
abbreviatis, dorsalibus 8 primis antice integris, 4 basali, suturali antice abbreviata ; propygidio parce, 
pygidioque tenuiter, punctatis ; prosterno vix lato, bistriato, antice marginato ; mesosterno stria marginali 
_subintegra, transversa, sed leviter impressa. Long. 3 millim. 
Hab. Nicaragua, Chontales (Janson). 
A single example. This fine species is much larger than P. violaceus, Mars., and 
differs from it in the dorsal strie, and, more especially, in the posterior transverse 
stria of the mesosternum, this stria being lightly impressed, nearly straight, and not 
crenulate. In P. violaceus the last-named stria is arched, crenulate, and finely cut.
