Head more than twice as wide as long, 2 nun.: 5 mm. Anterior mar- gin widely rounded. Eyes large and round, composite, and situated close to the lateral margins. First pair of antennae incon- spicuous and rudimentary and composed of two short, subequal articles and a mi- luite terminal article. The first antemue extend onh' to the end of the first article of the peduncle of the second antenniv. The first two arti- cles of the second pair of an- tenna? are equal in length; the third is nearly twice as long as the second; the fourth is one and a half times longer than the third; the fifth is one and a half times longer than the fourth. The flagellum is composed of twelve articles. The second pair of antenna? extend to the middle of the fourth thoracic segment when retracted. The maxilliped has a palp of five articles. The first four segments of the thorax are subequal; the last three are somewhat shorter in the median dorsal line. The lateral portions of the last three segments extend downward. The epimera of all the segments are broad plates, occupying the whole of the lateral margins of the segments and indicated by dis- tinct lines. The abdomen is as wide as the tho- rax, the lateral parts of the third seg- ment extending as far as the lateral parts of the seventh thoracic seg- ment. The lateral parts of the first two segments of the abdomen are not developed; those of the last four segments are well developed and have the posterior angles produced downward. The lateral parts are not separated off from the dorsal portion of the segments. On the lateral parts of the third, fourth, and fifth se
