Larra aurantia n. sp. 



9 . Black, the abdomen orange. Head and thorax with exceedingly 

 fine, even punctures; front with a faintly impressed line, which begins at 

 the base of antennae and extend to the anterior ocellus, beginning again 

 from a strong curved foveae, behind the posterior ocelli, it extends to the 

 top of the vertex; the space between the ocelli much swollen, with a deep, 

 curved sulcus on each side, which almost connects with the foveae behind 

 the posterior ocelli; the face somewhat excavated on each side, behind 

 the base of the antennae; the anterior portion of the clypeus shining, 

 strongly punctured, with a transverse furrow before its margin, which has 

 an exceedingly slight tooth each side just before its lateral angles; eyes 

 strongly converging towards the top, the distance between them at this 

 point barely equal to the length of the second and third antennal joints 

 united; antennae shorter than head and thorax together, tapering to the 

 apex, flagellum brownish, with a microscopic pile; scape short and stout, 

 narrowed one-half towards the base, in length about equal to the third 

 antennal joint, this latter joint is about four times longer than the pre- 

 ceding one, and about equal to the following joint, the fifth and sixth 

 joints longest; scutellum and post-scutellum with a very faint medial im- 

 pressed line; metathorax above finely roughened, with a few indistinct, 

 longitudinal striae at the base, the posterior face more strongly roughened, 

 with a distinct medial sulcus, which is broadest basally, the furrow not 

 reaching to the apex; wings fusco-hyaline, nervures dark, the distance 

 between the first transverse-cubital nervure and the first recurrent nervure 

 is greater than the space between the first and second recurrent nervures 

 on the cubital nervure. Legs black, finely punctured, the tibial spurs and 

 the tarsi ferruginous; posterior femora within glabrous. Abdomen orange, 

 the apical margins of the segments subopaque, beneath it is marked with 

 dark blotches; pygidium with a few scattered punctures, towards the apex 

 with sparse, bright hairs. Length 14 15 mm. 

 Two specimens; Montana. 



Larra punctifrons n. sp. 



9, Black, slightly shining; sides of the face and thorax with sparse, 

 silvery-sericeous pile. Head and thorax with fine, even punctures, more 

 fine on the cheeks and pleurae; clypeus strongly convex, the posterior 

 half finely punctured and subopaque, the anterior half polished, and with 

 large scattered punctures, a transverse furrow before the anterior margin, 

 the latter being polished and entire; front bituberculate above the antennae; 

 a distinct impressed line begins immediately behind the tubercles and ex- 

 tends to the lower ocellus, beginning again behind this ocellus, it passes 

 up through a strong swelling between the posterior ocelli to the base of 

 the occiput, behind the posterior ocelli there is a strong foveae; eyes 

 strongly converging towards the top, the distance between them at this
