second ventral segment formed as in that genus; the pro- 

 notum sunk below tiie tnesonotuni, distinctly higher in the 

 middle than on the sides ; and a small tooth on the inner side 

 of the mandibles at about one-third from the base. On the 

 other hand, it approaches Larra in the short tarsal ungues 

 and iti the very sparse pubescence of the pygidial area.

 • Tachytes australis, Sauss., Keise d. Novara, Zool. ii. p. 68 

 (1867), is quite a different insect, but has been confused in 

 Dalla Torre's catalogue. It is probably a Tachyspkex. 



Notogonia jnlosifrons, sp. n. 



$ . Nigra, fronte aureo-pilosa, segmentis dorsalibus 1-3 fascia 



apicali obscura albida ; alis f uscis. 

 Long. 17 mm. 



? . Clypeus subopaqup, very minutely and closely punc- 

 tured, with a transverse row of large punctures luar the apex, 

 the apical margin straigiit. iSecond joint of the flagellum 

 equal to the tliird, twice as long as the first. Eyes separated 

 on the vertex by a distance equal to nearly two-thirds of the 

 length of the second juint of the flagellum. Front clothed 

 with bright golden pubescence. Fronotum sunk much 

 below the mesonotum, much higiier in the middle than at the 

 sides; mesonotum strongly depressed in the middle of the 

 anterior margin, subopaque. Medicui segment opaque, longer 

 than broad, obscurely transversely striated, the striae more 

 distinct on the apical angles and on the posterior truiicatioti ; 

 a very ob.scuie median carina from the base not reacliing the 

 apex. Abdomen subopaque ; the pygidial area triangular, 

 the sides a little longer than the base, covered densely with 

 coarse black setse. First ventral segment finely obliquely 

 striated at the apex; second ventral segment swollen towards 

 the base, as is u.sual in the genus, and with a carina from the 

 base not reaching the middle. Jiasal joint of the fore tarsus 

 with four spines on the outer margin. Second abscissa of 

 the radius a little shorter than the third, in some specimens 

 equal to the third ; the two recurrent nervures very near 

 together on the cubitus.

The wings are paler than in N. gowdf^yi, Turn., and have 

 no blue effulgence. It is also distinguished from tiiat species 

 by the golden pubescence on the front, the sculpture of the 

 median segment, the lesser distance between the eyes on the 

 vertex, and otiier ■ etails.
