towards the apex ; and the wings more clearly hyaline, with the second cubital cellule 

 longer compared with the third. The third antennal joint is less than one quarter 

 shorter than the fourth. The tips of the tarsi are rufous. 



NOTOGONIA. 



Notogonia, Costa, Ann. Mus. zool. Univ. Napoli, iv. pp. 80, 82 (1868). 

 Larrada, Smith, Cat. Hymen. Ins. iv. p. 273 (partim) . 

 Larra, Patton, Proc. Bost. Soc. Nat. Hist. xx. p. 385. 



This genus appears to be much more numerous in species than Larra and has an 

 equally wide distribution. The species are very difficult of discrimination, and I have 

 been compelled to leave over for future study many specimens which no doubt represent 

 different species from those here enumerated.

Hob. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



Eyes separated at the top by scarcely the length of the third antennal joint. 

 Antenna? as long as the thorax, covered with fuscous pile ; scape with pedicle as long 

 as the second and third joints united, finely transversely striated; second joint 

 considerably narrowed in the basal half, curved, more than one third of the length 

 of the third joint; the latter dilated at the apex, and a very little longer thaii the 

 fourth, which again is a little shorter than the fifth. Head above the antennae finely 

 shagreened ; face and clypeus closely punctured. Clypeus broadly projecting in the 

 centre; the apex depressed, almost impunctate, and with a row of fovese above the 

 depressed part; the centre with a very slight incision. Mandibles strongly punctured 

 at the base, aciculated at the apex. Palpi black, whitish at the apices of the joints, 

 and covered with whitish hair. Face and clypeus covered with fulvous pile of moderate 

 length and thickness. Thorax opaque, finely coriaceous, the scutellum very slightly, 

 the pro- and metathorax more strongly than the mesothorax. Anterior part of the 

 pronotum broadly raised, and with two elongated fovese on the top ; in length fully 

 three fourths as long as the posterior part (counting to the elongated apex). A 

 depression separates the anterior and posterior portions of the pronotum, the whole 

 being not much shorter than the head ; the anterior part bears a longish dark fulvous 

 pile, and the posterior part is silvery-sericeous ; and the propleura at its point of junction 

 bears a fringe of fulvous hairs. Meso- and metathorax opaque, scarcely pilose, except 

 on the sternum and on the apex of the metanotum. Mesonotum but slightly convex 

 in front, and not depressed in the middle; metanotum with a furrow down its entire 

 length (except at the top of the apex), the apex oblique (but not sharply), and having
