parallel, scarcely extending before the eyes. Frons medianly 

 keeled, and ( with the exception of narrow, laterally rounded, 

 lateral margins which are a continuation of the lateral margins 

 of the vertex ) raised, sloping flatly backwards and upwards, a 

 I)art of the base, nearly as long as the vertex, being visible dor- 

 sally in front of the latter. This dorsal part of the frons is 

 semicircular and impressed entirely within the margins, and. as 

 implied above, is narrower than the vertex. Antennae small. 

 Pronotum transverse, wider and a little shorter than the head, 

 roundly arched anteriorly, slightly emarginate posteriorly. Scu- 

 tellum bicarinate. Tegmina strongly decumbent, medianly con- 

 vex, reaching posteriorly much farther than the aljdomen. Costal 

 cell broad, with cross veins ; the radial and median springing from 

 a common, short stalk, close to tlie brachial, but soon forking, 

 the radial almost immediately refoiking. The venation is rather 

 obscure and ill-defined in places. There is no proper subapical 

 line. The costal vein runs almost at right angles to the body, 

 then curves roundirgly to form the apical margin, almost at right 

 angles again, meeting the commissure at, apparently, a very acute 

 angle. Wings rudimentary ( ?). Hind tibiae with one spine. 



I . soiioraiia sp. nov. 



Brownish testaceous; a broad, dark fuscous stripe running from 

 apex of head (dorsall}) to hind margin of scutellum. Tegmina 

 opaque, coriaceous, pale brownish yellow, veins partly concolor- 

 ous, partly dark fuscous. 



Length about 3^ mill. 



HAB. Arizona, Nogales ; (Koebele's no. 2498). 



Only one specimen m bad condition, unfortunateh, , of this 

 curious form ; it is parasitized. 



It is very Issine in appearance, but the granulation of the clavus 

 and the structure of the head proclaim it to be Poekiliopterine. 

 It is probably allied to Hypancyiiis Fowler, which that author 

 places, apparently incorrectly, in the Issinae.
