'Clypcus convex, smooth, slightly rounded out on the anterior margin ; front shining, very finely sculptured, bearing no impression ; anterior occllus about on a iine with the pos. terior margin of the eve, distancebetween the posterior ocelli less than the distance between them and the nearest eye margin ; pdicelium nearly as long as the first two joints of the flagellum, joints of the fiageilum subequal ; pronotum smooth with no sharp margins; dor- sulum sculptured much like the front, in addition it has some sparse rather distinct fine punctures ; mesopleurae sculptured like the dorsulum ; inetathorax dull granular, flat, with two longitudinal raised lines fairly close together ; abdomen shining, apparently impunc- rate ; pubescence pale, inconspicuous.

A NEW SPECIES OF ROACH OF THE GENUS KAKERLAC (LOBOPTERA AUCT,) FROM SOUTHERN TEXAS.
8V JAMES A. G. REHN, PHILADELPHIA, PA;
RECENTLY Mr. C. Schaeffer, of the Brooklyn Institute of Arts and Sciences, submitted to the author for determination a single specimen of a species of the genus Kakerlac (hhpfera of authors).
On comparison with
the figures and
descriptions of the previously known species of the genus it appears to be new. Kakerlac schaefferi n. sp.

amis it can be separated by the narrower form, broader tegmina and comparatively longer pronotum.
Size small ; form elongate ovate, depressed ; surface glabrous. Head rather
narrow, the anterior margin extending beyond the pronotum ; interspace between the eyes broad, but slightly less than that between the antenna1 bases, tumid ; eye subreniform, depressed; antennae short, not quite equal to the body in length, flagelliform. Pronot urn with the length less than the posterior width, moderately arched; anterior margin subtruncate, posterior truncate, lateral margins straight with the anterior angle very broadly rounded and the posterior rectangulate, with the extreme angle rounded. Mesonoturn with the posterior margin truncate ; met- anotum broadly and shallowly emarginate. Tegmina short, but slightly exceeding .
the mesonotum, narrow, hastate; apex bluntly angulate ; internal margins separated by a space almost double the width of the single tegmen. Abdomen broader than the thorax ; supra-anal plate truncate, very broadly obtuse-angulate ; cerci short, slightly longer than the supra-anal plate, fusiform, apex rather attenuate ; subgenital plate rather large, not projecting beyond the supra-anal plate, apical margin evenly arcuate. Anterior femora with the anterior inferior margin bearing four median spines and with the apical portion finely spinulose, posterior margin unarmed; tibiae but slightly more than half the length of the femora. Median femora bear- ing three spines on the anterior margin, one apical, two median, posterior margin bearing six spines of which the apical are smaller than the median ; tibiae slightly shorter than the femora.
Posterior femora with the anterior and posterior margins each armed with three spines, two median and one apical ; tibiae slightly longer than the femora ; posterior metatarsi slightly longer than the remaining tarsal joints. General color black becoming burnt sienna on the limbs, cerci and margins of the thoracic segments.
