Allied to M. sumatrensis Brancsik^^ from Sumatra, but differing in 

 the shorter mesonotum, the compressed ninth abdominal segment, the 

 non-annulate antennae and the different color pattern of the tegmina- 

 Brancsik's Necroscia papuana from Xew Guinea and Westwood's 

 ismene from Borneo are apparently related to phluctainoidcs , but very 

 distinct species. 



d*. — Size rather small; form slender; surface of head subgiabrous, 

 of thoracic segments granulose. Head rather large, moderately de- 

 pressed, somewhat inflated, the posterior portion subequal in width, 

 occiput with a faint median sulcus; eyes ovate, prominent; basal joint 

 of the antennae slightly depressed, longer than broad, second joint 

 longer than broad and not equal to the basal joint in size, total length 

 of the antennae about equal to that of the abdomen. Pronotum quad- 

 rate, with a fine median longitudinal sulcus and a well-marked trans- 

 verse sulcus which is placed before the middle. Mesonotum somewhat 

 over three times the length of the pronotum, subequal anteriorly, 

 slightly expanded posteriorly, very distinct median and lateral carinae 

 present, all becoming rather evanescent posteriorly, surface rugoso- 

 tuberculate. Tegmina short, subtruncate apically, raised portion of 

 moderate elevation, rounded. Wings large, damaged in the type, 

 but apparently reaching the apex of the abdomen in the perfect speci- 

 men. Abdomen slender, the six basal segments longitudinal and 

 slightly decreasing in length apically; eighth segment slightly longer 

 than the seventh, both carinate, the seventh slightly expanded apically, 

 the eighth slightly compressed; ninth segment about equal to the sev- 

 enth in length, compressed, subtectate, apex truncate when viewed 

 from the dorsum; cerci about reaching to the apex of the ninth seg- 

 ment, subequal, slightly incurved; supra-anal plate absent; subgenital 

 opercule reaching to the apex of the eighth dorsal segment, rotundato- 

 truncate. Anterior femora somewhat exceeding the pronotum and 

 mesonotum in length, considerably curved basally; tibiae slightlj'- 

 shorter than the femora; metatarsi very slender, equal to the remaining 

 tarsal joints in length. Median and posterior limbs absent. 



General color purplish-brown, rather pale on the proximal portion 

 of the anterior femora. Tegmina with the elevation black, bordered 

 laterally by a longitudinal bar of pinkish-white, which extends to the 

 apex of the tegmina. Wings pinkish-purple. 



? . — Size medium ; form rather robust ; surface of mesonotum and 

 tegmina rugose. Head inflated, slightly elongate; eyes ovate, mod-
