104 NEOTROPICAL PSELAPHIDAE 



I take pleasure in naming this interesting species for my friend Mr. 

 James Zetek, resident custodian of the Barro Colorado Island Laboratory, 

 whose interest and aid made my trips to the Zone profitable and pleasant. 

 This species runs to the neighborhood of Acolonia Casey in the 1908 key to 

 genera of Raffray's great treatise. It is obviously not at all near to this genus. 

 On the other hand it is allied to Euplectus in many features, in general habitus, 

 pronotal outline, and tergite proportions, while differing from Euplectus in 

 having no transverse pronotal sulcus of any kind, lack of basal abdominal 

 carinae and other characteristics. Known so far by a single species, this genus 

 is very distinct: 



zeteki new species. Panama Canal Zone. 



VERABAROLUS neiv genus 



Euplectini having (1) vertex bifoveate; (2) eleven-segmented antennae 

 which are widely separated at base, and with a three-segmented club; (3) 

 maxillary palpi well-formed, four-segmented, first short and cylindrical; sec- 

 ond arcuate, elongate, narrow at base and apically inflated; third short, trans- 

 versely triangular; fourth long, nearly twice as long as eye, subsecuriform ; 

 (4) pronotum obcordate, lateral margins not dentate; lateral fovea each side 

 at basal third, and a median subbasal fovea connected by a biarcuate, trans- 

 verse, subbasal sulcus ; disc with an elongate median fovea or linear groove, not 

 reaching apical margin or subbasal transverse sulcus; (5) each elytron with 

 four basal foveae, non-denticulate humeral angle; flank with subhumeral 

 fovea and a subepipleural carina which is parallel to elytral margin ; no dorsal 

 stria, but an entire sutural stria; (6) abdomen of five visible tergites, these 

 with no basal discal carinae, and subequal in length, being slightly progres- 

 sively shorter; six visible stemites in the female sex (male unknown), second 

 to fifth sternite progressively shorter; (7) middle coxae subcontiguous, allowing 

 the mesosternal and metastemal processes to be discerned between them; 

 (8) posterior coxae contiguous; (9) prostemum not medianly longitudinally 

 carinate, but medianly gibbous, this gibbous area being posteriorly prolonged 

 to form a short carinoid line in basal third, between lateral prosternal foveae; 

 (10) tarsi three-segmented, first minute, second and third much larger, second 

 longer and thicker than third, third with a single claw.
