It has become necessary to review certain segments of the Neo¬ 
tropical fauna in conjunction with our studies on North American 
Lamiinae. Several of the more interesting and significant new species 
are described below. 
This work was carried out during the course of a National Science 
Foundation-sponsored study on North American Cerambycidae 
through Grant GB-BM574. Celeste Green prepared the illustration. 
Peritapnia pilosa, new species 
Male: Form moderate-sized, depressed, integument black, shining. Head densely 
micropunctate with larger punctures sparsely interspersed, each puncture bearing a long, 
erect seta; antennae extending about three segments beyond elytra, scape gradually 
enlarging toward apex, segments three to six stout, third segment shorter than first, 
fourth equal to third, fifth subequal to fourth, segments densely clothed with fine, ap- 
pressed pubescence, basal segments with several, long, erect hairs at apices. Pronotum 
broader than long, sides angulate, acutely tuberculate at middle; disk slightly convex, 
densely micropunctate with larger seta-bearing punctures sparsely interspersed; 
prosternum transversely rugulose, glabrous, intercoxal process barely arcuate, about 
one-third as broad as coxal cavities; meso- and metasternum barely punctate, densely 
clothed with very fine appressed pubescence. Elytra about 11/z times as long as broad; 
punctures behind scutellum large, subconfluent, extending along suture to middle, other 
basal punctures irregular, smaller, all punctures becoming very fine toward apex; erect 
setae arising out of large punctures at least twice the length of second antennal segment, 
underlying pubescence dense, fine, appressed; apices narrowly rounded. Legs densely 
micropunctate, finely, densely pubescent. Abdomen micro-punctate with a few larger 
punctures interspersed; last sternite rounded at apex. Length, 9 mm. 
Female: Form similar. Antennae slightly shorter. Abdomen with last sternite excavated 
at middle, the depression bounded posteriorly by a transverse, arcuate carina. Length, 8-9 
mm. 
Holotype male (California Academy of Sciences) from 56 miles NW Tehuantepec, 
Oaxaca, Mexico, 27 July, 1963 (J. Doyen). Two female paratypes from 23 miles S. Matias 
Romero, Oaxaca, 14 August, 1963 (F.D. Parker and L.A. Stange). 
The long, erect setae of the head and elytra will separate this 
species from other Peritapnia. 
Peritapnia minima, new species 
Tapeina nudicornis Horn, 1894:340 (not Bates 1885). 
Peritapnia nudicornis, Horn, 1894:403; Linsley, 1942:75. 
Male: Form small, depressed, integument rufo-piceous, appendages reddish brown.
