174 ENTOMOLOGICAL NEWS. [April, 'l6 



moderately long, the outer angles prominent, the posterior margin with 

 a slight median production, margins usually dark-marked. 



Color: vertex bright straw, or lemon yellow, a pair of angular black 

 spots well back of the ocelli and a pair of smaller ones behind these 

 near the base, occasionally a trace of transverse brown band on disc. 

 Face bright straw, sutures dark and occasionally a trace of brownish 

 arcs on front and a pair of spots near apex. Pronotum all clear straw 

 or dirty straw with the anterior light margin set off by dark spots. 

 Elytra pale subhyaline straw, the nervures inclined to be lighter. 



Described from four females from Logan and Richfield, 

 Utah, collected by the writer. The inflated shining front and 

 vertex gives this insect a distinctly "bald-headed" appearance, 

 which is its most distinctive character. 



Athysanus shastus n. sp. 



Size and form of rams, nearly resembling striatulus in pattern, bul 

 with fewer markings. Stout, rusty straw with darker margins. Length 

 4.5-5 mm. 



Vertex broad slightly roundly right-angled, with the apex narrowly 

 acutely produced, three-fourths the length of the pronotum. Front 

 broad not inflated, narrowing regularly into the broad clypeus. Face in 

 profile almost flat, acutely angled with the vertex. Pronotum long, the 

 anterior margin curving deeply into head. Elytra very broad and ex- 

 tending well beyond the pygofers, broadly rounding behind with short 

 apical cells. Venation strong, resembling arctostaphyll, but with a large 

 number of irregular cross nervures on clavus and occasional super- 

 numerary cells in the outer anteapicals, second cross-nervure often 

 present. Female segment broad, moderately long, truncate, the apical 

 angles slightly produced, pygofers very short strongly angularly in- 

 flated. Male plates together spoon-shaped, narrowed apically. 



Color: vertex dirty straw, a transverse black band just back of 

 ocelli, another just before this broken forward in the middle, both bands 

 inclined to be emphasized at the end and against a narrow median line 

 which bisects them; occasionally nothing is left but these enlarge- 

 ments. Front black with a triangle at apex and short arcs straw color. 

 The rest of face straw color with sutures and an oval spot on clypeus 

 dark. Pronotum rusty straw, darkening posteriorly to a dusky cloud 

 on disc, anterior submargin with a few irregular black marks. Elytra 

 smoky subhyaline, the nervures light, very narrowly lined with fuscous, 

 emphasized in the smaller cells. 



Described from two females and two males from Dunsmuir, 

 California, collected by the writer. The broad form with short 

 inflated pygofers renders this distinct species somewhat of a 

 connecting link between the obsolctus and striatulus groups.
