BRACHYGLUTINI 129 



more transverse than in politus, and the eleventh segment 

 thicker than politus, and cited as being less than half the length 

 of the antenna. Antennal segment IX lenticular, X transverse 

 and twice as large as ninth, XI large and conical. 



The general habitus and structural detail of the genotype, glaber, is de- 

 picted in the plates. Raffray (1908, 1909) has already remarked on the tychine 

 character of the fourth segment of the maxillary palpi, this segment being 

 slightly securiform. 



The shining, glabrous, short and thick body, general lack of punctures and 

 setae on the integument, the yellowish to reddish-yellow color, the subcontig- 

 uous posterior coxae, slightly securiform and large distal segment of the max- 

 illary palpi, and the exceptionally large and melbaform eleventh antennal seg- 

 ment give a constant habitus to the genus. 



The species may be listed as follows: 



dominicanus Schaufuss. 1887. Hispaniola. 



gibbicollis (Raffray). 1896. Mexico. {Euprenius Raffray nee LeConte) 

 gracilis Raffray. 1904. Grenada, Windward Islands. 

 grouvellei (Raffray). 1896. {Euprenius) Mexico. 

 longioollis (Raffray). 1896. (Euprenius) Colombia. 

 mexicanus (Raffray). 1896. (Euprenius) Mexico. 

 politus Reitter. 1883. St. Thomas, Virgin Islands and Guadeloupe, 

 Leeward Islands. 



EUPSENINA (Raffray, 1909) 



Eyes large, set in a trapezoidal head, the ventral surface of which is devoid 

 of longitudinal median carina or large median fossa. The maxillary palpi are 

 minute, the first segment very minute, second slender at base and swelling 

 apically where it is abruptly clavate, third small and globose, fourth subsecuri- 

 form, subovate. Eleven-segmented antennae with the first segment elongate 

 and cylindrical, the antennae subgeniculate between the long first and the 

 shorter second segment, which varies in shape between the species from globose 

 to triangular, third to eighth small, moniliform, ninth and tenth lenticular, cres- 

 centric, the eleventh segment relatively enormous. Pronotum subcordate. Elytra 

 relatively very wide. Abdomen with tergites subequal, and with six sternites. 

 Other differences are notable but are discussed in the description of a new 

 species. 



The genus is not discussed in the Genera Insectorum, so a rather free trans- 

 lation of Raffrey's remarks is not out of order: 



"This genus is very aberrant and extremely near Eupsenius, which it resembles 

 in habitus, and hardly differing at first sight with its geniculate antennae; but 

 differing from Eupsenius by the smaller palpi, of which the last segment is 

 more acuminate; ventral surface of the head does not have the lateral carina
