cophorus cicatr^kosus M.at'&chwl^li.y — Calocems cicatrlcosus (Mot- 

 schiilsky) (designated by Blackwelder, 1942). 



Diagnosis. — Body rather cylindrical and elongate; head strongly 

 rounded and constricted behind the eyes; antennae stout, outer seg- 

 ments transverse, all but one or tMO at base sculptured and pubes- 

 cent ; labrum very short, four times as wide as long, more or less 

 tuberculate at sides; third segment of maxillary palpus much en- 

 larged, fourth acicular; gular sutures entirely absent; anterior coxae 

 small and globose, separated by a process of the prosternum ; anterior 

 coxal cavities nearly closed behind by processes of the inflexed pro- 

 notum; mesoternum very small, not connate with metasternum be- 

 tween the middle coxae; posterior coxae small and globose, not ex- 

 panded laterally beneath the femora; abdomen not margined; ster- 

 nites of first and second segments not present ; trochanters all attached 

 to end of femora; femora and tibiae unarmed; tarsi 3-segmented. 



Remnrks. — There has been no diagnosis of this genus published 

 heretofore so far as I am aware. These characters were taken from 

 G. tiinMad^'n.ns and specimens of G. crlhcUn^s Sharp in the United 

 States National Museum. 



I have examined only the 10 examples from Trinidad and the 

 Central American ones. 



KEY TO WEST INDIAN SPECIES OF GLYPTOMA 



1. Elytra unifostate 2. guadelupensis 



Elytra without longitudinal costae 1- trinidadensis 



1. GLYPTOMA TRINIDADENSIS, new species 



DesGi'i'ption: — Rufocastaneous to rufotestaceous. Head a little 

 more than one-fifth wider than long, rounded behind the eyes; supra- 

 antennal prominences feeble; with moderately coarse punctures on 

 the vertex, separated by once to twice their diameter, much sparser 

 anteriorly; smooth, without ground sculpture. Pronotuuh (me-ninth 

 wider than long, one-tenth narrower than the head, widest in front, 

 scarcely narrowed to middle, but thence strongly to base; margin 

 feebly crenulate; disk behind middle on each side of mitlline with 

 a deep impression formed of two punctures united; with similar im- 

 pressed punctures, usually smaller, at the sides, and sparsely in front. 

 Elytra a little more than one-half longer than pronotum, two-fifths 

 wider than pronotum, slightly widened posteriorly; each with a 

 smooth, rounded, longitudinal elevation, but not at all costate; on 

 each side of ridge and near outer margin with rather indefinite rows 

 of moderately large punctures, more or less united and occasionally 

 interrupted; without ground sculpture. Ahdonien without ground 

 sculpture; very coarsely punctate at base of segments. Length, 2i/4 to 

 21A mm. «
