appearaiice when viewed from the side. It is probable tliat the genus Blaltn will 

 have to be further subdivided, orientalis L., concinna Haan, and ((.ssiniensis BoL. to 

 take three examples, do not appear to be congeneric. 



Gen. Parainetliaiia nov. 



Differs from Donjlaea ' Stäl in the size of the second pulvillus of the posterioi- 

 tarsi whieh Covers the whole second Joint, and differs froni Methana Stäl in the 

 reduction of the tegmina and wings which do not extend be_yond the fifth abdominal 

 tergite. Third antennal Joint nearly three times as long as the second. 



Paraniotliaua rolnisla sp. n. 



(IM. 2, «M. 7.) 



?. Dark castaneous, nitid, broadly elhptical. Head castaneous, clypeus and 

 mouth-parts rufo-testaceous, eyes less remote than antennal sockets, antennae fuscous, 

 except the two basal joints which are rufo-testaceous; Vertex of head not covered 

 by pronotum. Pronotvnn broad, trapezoidal, sides deflexed, posterior margin sinuate, 

 castaneous with a central rufo-castaneous mark, or rufo-castaneous with darker 

 castaneous marks. Tegmina short and broad, overlapping considerably, semi-corneous, 

 veins well-marked, mediastinal vein bifurcate, 9 costals, the last three ramose, anal 

 vein deeply impressed, reaching sutural margin at a point one-third from apex. 

 Wings a little shorter than tegmina, flavo-hyaline, apex slightly infuscated. Abdomen 

 piceous above, castaneous below, posterior angles of penultimate tergite strongly pro- 

 duced, its posterior margin slightly produced, sinuate; supra-anal lamina produced, tri- 

 angulär, apex emarginate and deeply cleft. Cerci long, subacuminate, of thirteen joints. 

 Legs rufo-castaneous, front femora with a complete row of spines on anterior margin 

 beneath; tibial spines in three rows; posterior metatarsus exceeding remaining joints 

 in length, bi-spinulose beneath, pulvilli of remaining joints large occupying the whole 

 extent of the under surface of the joints. Total length 23 mm.; length of tegmina 

 13 mm.; pronotum 7 mm. x 10,i mm.

' The type of the genus Donjlaea is hniniierl Stäl. a specics closely allied to fhtriciiicfa Uxxs; botli 

 species are characterized by peculiar maxillary palpi aml by the siiiall size of the second i)ulvillus of the posterior 

 tarsi; these are good generic characters. In Biol. Centr. Amer. Ortli. I, p. 69, 1893, de Saussuke aud Zeiintnek 

 re-define the genus BortiJueu and transfer to it the apterous species rlwmbifolia Srou,. which is eertamly uot 

 congeneric with flavicindu Haan and hrunneri St.\i.. This procodurc is ([uite uiinocessary. rhmhifoUa is a 

 characteristic species of the genus Stylopyi/a, no useful purposc i< «jerved i>y forciiiir it into a wnu^ tliat alrcady
