OSBORN AND BALL — STUDIES OF NORTH AMERICAN JASSOIDEA. 57 



Genitalia: V, ultimate ventral segment long, lateral margins par- 

 allel, posterior margin produced one-half the length of the segment on 

 the middle, sloping away to the lateral angles, tip slightly but distinctly 

 notched; p\ gofers stout, two and one-half times the length of the seg- 

 ment, slightly exceeded by the oviducts. 



Desciibed from three females, Vera Cruz, Max. (Osborn). Readily 

 separated from the other two of the section by the genitalia and length 

 of elytra. 



Larva: Form similar to that of novella, vertex longer, nearly 

 equaling the pronotum in length, reddish-brown with light spots in 

 four longitudinal rows. Vertex widening from eyes obliquely upward 

 and forward in a plane with the face, upper margin acute, roundingly 

 lobed. Vertex, front and clypeus forming a concave-margined wedge, 

 thorax much as in novella, abdomen with two weak lateral carinae, 

 reddish brown with a light upper margin to the vertex, four white 

 bristle-bearing tubercles on the posterior margin of each thoracic and 

 abdominal segment. 



Agallia oculata V. D. 



Ent. Amer., VI., p. 38, 1890. 



Species large, stout, much broader than tenella, xfitxi\\)\\x\g producta 

 in form and size but easily distinguished by the central position of 

 the pronotal spots, and the curvature of the vertex. Length, 4.50 

 mm..; width, 1.50 mm. 



Vertex rather broad against the eye, nearly regularly narrowing to 

 the middle, where it is simply a line, posterior margin produced 

 around behind the eye, then slightly expanded and convexly rounding 

 to lorse. Frontal suture slightly curved, front very broad at base, 

 three times width on clypeus, wider than long, sides slightly con- 

 stricted above the middle. Pronotum long, the posterior margin 

 short, truncate, humeral margin long rounding to the eye, more than 

 half the length of the pronotum within the curve of the vertex. Elytra 

 long convex in front, narrow behind, veins on clavus approaching in 

 the middle. 



Color: Fulvous-brown, spots on vertex and pronotum black, nerves 

 of elytra lit;ht, interrupted by dark-brown bands, vertex light-fulvus 

 with a median line, two large spots on the disc, a pair of smaller ones 

 against each eye, black; sides of front, tip of clypeus and facial sut- 

 ures dark-brown. Pronotum fulvous, a large spot near the center of 

 either side, black, a median line, a small spot on either side of it near
