1. INOPEPLUS WOLCOTTI, new species 



DescHption. — Pale riifotestaceous. Head arciiatel}^ narrowed be- 

 hind the eyes; moderately coarsely bnt shallowlj^ punctate; punctures 

 separated by once to twice their diameter; surface slightly uneven but 

 without ground sculpture except on the clj^peus; midline feebly but 

 distinctly impressed througli most of its length. PronotvAii slightly 

 narrower than head behind the eyes, a little more than one-fourth 

 wider than long; base a little less than one-half as wide as apex; sides 

 only feebly interrupted at basal and apical third by impressions of 

 the margin, the impressions marked posteriorly by a circummarginal 

 ridge but not actually excavated as a pocket; midline very finely and 

 a little irregularly channeled ; punctures rather coarse and irregular, 

 frequently separated by less than their diameter; without ground 

 sculpture. Elytra narrower at base than pronotum but fully one-half 

 wider at apex than at base; impunctate (except vaguely at sides) and 

 without ground sculpture ; extending about one-third their length be- 

 yond metasteriuim. Ahdoinen above impinictate. Length, 3 mm. 



Type locality. — Haiti, Acpiin, on the south coast of the southwest 

 IDeninsula. 



ry/;^^.— Holotype, female, U.S.N.M. No. 52360, collected by G. N. 

 Wolcott in March 1927. 



Records. — The following is the only record known to me : 



Hispaniola: Haiti: Aquin (Wolcott, in U.S.N.M.). 



Specimens examined. — I have seen only the unique type. 



Remarks. — This specimen is complete although somewhat collapsed. 

 The elytra may be slightly infuscate apically, though this seems to be 

 due to transparency. The specimen was borrowed from the Service 

 Technique in Haiti and is retained in the United States National 

 Museum collections through the Ivindness of Andre Audtmt. 



I have no record of the habits of this species. 



2. INOPEPLUS MUTCHLERI, new species 



Description. — Flavous, head slightly rufescent, apical lialf of elytra 

 cinnamomeous except for the margins. Head moderately punctate, 

 punctures usually separated by less than their diameter; with traces 

 of groimd scul])ture in feeble median depressions; sides behind eyes 

 sti'aight but sti'ongly converging. Proriotmn about as wide as head
