328 NEOTROPICAL PSELAPHIDAE 



Elytra as in veracruzensis. 



Tergites margined as usual, in a length ratio of 3.5/3.5/2.5/2.5/2 with the 

 last tergite rounded-triangular. 



Stemites in a length ratio of 1.5/2.5/2/1.5/1/1.5 with the last five much 

 more concave medianly to form an elongate-oval depression. The sixth sternite 

 is notably large, trapezoidal, coarsely punctate and deeply depressed medianly. 

 The penis is partially extruded so that the sex of the type is verifiable. 



Metastemum, coxal separation and legs as in veracruzensis save that the 

 anterior trochanters are not toothed but instead the ventral face is compressed 

 into a longitudinal blackened carina. 



Described from a single male specimen from San Juan, Vera Cruz, 

 Mexico, collected by C. H. Seevers on July 13, 1941. 



In the Raffray 1904 key this species becomes associated with sanguinipes 

 Rafifray of French Guiana, with which it has little affinity save common 

 position in Group XII. 



Hamotus {Hamotoides) thomasi new species 



Type. Measurements: 2.11 mm. long x 0.80 mm. wide. Shining reddish- 

 brown; pubescence and punctation as in electrae. (PI. VI, XVII) 



Head as in electrae save that the eyes have about 34 facets each and are 

 distinctly hirsute; median cephalic fovea more distinctly pubescent and with 

 the lumen obliquely dorsal, rather than apical as in veracruzensis. 



Antennae with segment I elongate-cylindrical ; II subquadrate ; III shorter 

 and narrower, longer than wide, obconical; IV-VIII as in electrae; club well- 

 formed: granulate-asperate as usual with IX trapezoidal, longer than wide; 

 X trapezoidal, wider than ninth and wider than long; XI as long as the two 

 preceding united, distinctly flattened so that the dorso-ventral diameter is 

 much greater than the latero-mesial diameter, and with the poroid tubercle 

 of its apico-mesial face well developed. 



Pronotum as in veracruzensis with a very small median fovea not much 

 larger than the transverse sulcus, but with the latter almost straight in the 

 median third of its course instead of sharply arcuate as in veracruzensis. 



Elytra as in veracruzensis. 



Abdomen with five visible tergites in a length ratio of 4/4/2.8/2.2/2 of 

 which the first three are margined as usual and the last tergite is transversely 

 trapezoidal. 



Six sternites in a length ratio of 1.5/2.5/2. 5/1. 8/1/.5 with the stemites 

 deeply separated, convex antero-posteriorly and slightly flattened medianly. 

 Metastemum as usual. Legs simple; trochanters simple, posterior tibiae not 

 spurred. 



The sex of the single specimen is unknown. It was collected from log 

 mold by C. H. Seevers on August 1, 1938 near Puerto Salgar, Cundinamarca, 

 Colombia. This species is a member of Group XIV, and within this assemblage
