144 NEOTROPICAL PSELAPHIDAE 



the glabrous dorsal face; VII elongate-cylindrical, slightly longer 

 than sixth, much narrower, and distinctly longer than eighth segment 

 but of the same width ; middle coxae each with a broad, triangular 



laminoid spine fovearthra new species (PL XVI, 13, 14) 



*6. Antennal segment V irregularly semilunar, with a sharp spine on the 

 internal face; VI a little smaller than fifth, nearly ovoidal, with a 



small tooth on the internal face eucera 



Antennal segment V with lateral face strongly convex, and mesial face 

 greatly produced, this production being arcuate so that the ex- 

 tension is an acute production of the internal apical angle which 

 bears several short setae; VI with a very narrow base, and an ir- 

 regularly pyriform, swollen apical two-thirds, the lateral face being 

 very rounded, the mesial face being nearly straight, with this latter 

 face bearing a short, blunt spine which is also equipped with sev- 

 eral setae; 1.8 mm. long guadalupensis 



Reichenbachia fovearthra new species 



Holotype Male. Measurements: head 0.29 x 0.37 mm.; antennae 0.84 mm.; 

 pronotum 0.37 x 0.40 m,m.; elytra 0.62 x 0.73 mm.; abdomen 0.47 x 0.71 mm.; 

 total length 1.8 mm.; greatest width 0.73 mm. (PI. XVI, 13, 14). 



Yellowish-brown, the integument shining, punctulate; pubescence moder- 

 ately abundant, longer (0.03 mm. long) on abdomen than on the elytra, 

 pronotum and head (0.02 mm. long). Head with the prominent eyes (34 large 

 facets) longer (0.107 mm.) than tempora (0.07 mm.). Vertex evenly convex, 

 with three large, subequal, pubescent foveae, each lying in a depression, two 

 being on a line through the middle of the eyes, mutually more distant than 

 each to the nearest eye, and a third median anterior fovea between the anten- 

 nal insertions. Front regularly declivous but not vertical; epistome simple; 

 labrum simple. Ventral surface of head flattened, with the usual longitudinal, 

 median, carinoid elevation typical of genus. 



Maxillary palpi typical of genus, as for stroheckeri save that the fourth 

 segment is slightly obliquely truncate at apex. 



Antennae abnormal, eleven-segmented, separated by a distance equal to 

 the mutual separation of the inter-ocular foveae; segment I irregularly elongate- 

 cylindrical, dorsal surface concave; II subspherical, as wide as first but 

 shorter; III much narrower and shorter than second, transversely obconical; 



IV shorter and wider than third, transversely ovate, the mesial face subacute; 



V very large and complex, transversely subquadrate, dorsal face strongly convex 

 longitudinally ; laterally this curvature gives a semilunar outline to the segment, 

 ventral face with a very large, densely setose, irregularly biarcuate excavation 

 occupying apical half from side to side; VI abnormal, much smaller than 

 fifth, excentrically articulated, transversely subovate dorsal face, ventral face 



* These two species, eucera and guadalupensis, are the only two of this forty-first group 

 known to inhabit the Antilles, and are very closely related.
