the genitalia; from constricta by the larger size and the much more 

 produced ? segment. 



A larva collected at the same time evidently belongs to this section 

 of the genus, and from its large size apparently to this species, and 

 will be described here. 



Larva: Form very similar to that of ^-punctata, slightly larger 

 with the anterior " horns " much more produced, resembling the 

 structure found in the beetle, Boletotherus bifurcus. Length, 3.25 mm. 

 Vertex much narrower than the prominent eyes which margin the pro- 

 notum on the sides, median third of vertex consisting of a thin, 

 slightly elevated plate with a broadly rounding anterior margin ; between 

 this and the eye, on either side, arises a long obovate anterior process 

 over three times longer than width at base ; these are slightly inclined 

 toward each other so that their elevated inner margins almost touch at 

 the broadest point. Pronotum over three times wider than long, an- 

 terior and posterior margins parallel, wing pads very long and nar- 

 row, abdomen short, laterally compressed, carinate as in 4-piinctata, 

 the whole surface armed with bristle-bearing papillae, largest on ab- 

 domen and on the margins of the anterior processes. 



Color: Obscure reddish-fuscous above, marked with white as fol- 

 lows: A narrow margin on the anterior processes, a large triangle on 

 the vertex, its base including all the anterior margin between the 

 horns, the apex continuous with a median line across the thorax, a 

 narrow line on the lateral margin of the pronotum extended back to 

 inner angle of the wing pads, a curved line just inside of these and a 

 few oblique lines on the wing pads ; beneath, fuscous, legs and genita- 

 lia lighter.

Narrow, wedge-shaped, testaceous-brown with four points on anter- 

 ior margin of vertex and two small sjjots just back c{ the middle of 

 the pronotum, black, the sutural margin of the elytra light, twice in- 

 terrupted with dark. Length, ? 3.75 mm.; width, 1.25 mm. c? 

 slightly smaller. 



Vertex very short, extended broadly around behind eyes until just 

 before the outer margin, where it is suddenly constricted, posterior 

 margin with the middle half abruptly elevated and carried forward.
