dilated below, black. Antennce black, with the scape flavous 

 beneath. Thorax closely aud somewhat strongly punctate, white- 

 pubescent and flavous, with a broad central stripe on the basal 

 two-tliirds of the mesonotum, uniting transversely at base with 

 an elongate line above radices, two semicircular basal metanotal 

 marks, an irregular mark below the radices, and an oblique apical 

 mark (obtuse at both extremities) on the mesopleui-ic below, black ; 

 metanotum subrugosely punctate and not areated, its apical slope 

 broadly impressed centrally. Ahdomen flavous, with a broad 

 fascia on the constricted base of the postpetiole, another basally 

 incised and apically transverse on centi-e of second segment, and 

 lateral spots together with the base of the following segments 

 broadly, and a central mark on the third to lifth ventral segmeuts, 

 black; basal segment nearly the length of the second and third 

 united, and distinctly widened apically; the following distinctly 

 not laterally compressed ; terebra 1 millim. in length. Leijs con- 

 colorous with the body ; hind coxae broadly at tiie base beneath, 

 their trochanters basally, femora externally towards and entirely 

 at the base and apex, and their tarsi (except the basal lialf of 

 metatarsus), black ; tibiae sparsely, and the tarsi more closely, 

 spinulose ; calcaria elongate and about three-fourths the length of 

 the metatarsus. Wini/s hyaline, with the stigma and nervures 

 black : areolet very small, elougately petiolate, emitting the re- 

 current nervure from its apex ; basal nervure not continuous 

 through the median ; hind wings with radius and cubitus sub- 

 obsolete, and external nervures obsolete. 



Length 9 millim. 



vSiKKiM (Col. Bingham), 



The abdominal segments are said to be distinctly broad com- 

 pared with those of Campoplex ; in fact, " the only difference 

 between this species and Campoplex oi much importance," says its 

 author, "lies in the abdomen not being strongly compressed, the 

 latter genus having also the metanotum longer and more or less 

 areolated." It differs from Echthronomas, Torster (A'^erh. pr. 

 Kheinl. 1868, p. 151), in having the calcaria very distinctly shorter 

 than the metatarsi. 



Genus RHIMPHOCTONA, Fdrst. 

 Rhimphoctona, Furster, Verh. pr. Klieinl. 1868, p. 153. 

 Genotype, Pyracmon fulvipes, Holmg. 



Head not cubical, broadly transverse aud but little constricted 

 posteriorly ; clypeus short, not discrete from the face and often 

 apically dentate in the centre. Autennee stout, setaceous and 

 fully three-quarters the length of the body. Thorax stout, with 

 the speculum somewhat dull ; metathorax declivous throughout 

 and a little produced apically, with distinct area3 ; costulse entire; 

 spiracles exactly oval. Seutellum not deplanate or margined. 

 Abdomen strongly compressed from base of the third segment ; 

 terebra elongately exserted. Legs slender, with the claws dis- 

 tinctly pectinate. Badial cell sublanceolate, nearly thrice as long
