THE CANADIAN ENTOMOLOGIST. 185 



Described from eight examples from Salinas, California. Collected 

 by the author. The distinct genitalia of either sex will readily separate 

 this species from the related forms. 



Koebelia irrorata, n. sp. — Form of Californica nearly, slightly longer 

 and with a longer and more pointed vertex. Head finely irrorate. Length, 

 ? , 7.5 mm.; $ , 6 mm. 



Vertex as long as its basal width, the lateral margins parallel before 

 the eyes, then rounding evenly to a blunt point. Front narrower above 

 than in Californica, the margins straight. Elytra longer and narrower 

 than in that species, not quite covering the ovipositor in the female. 

 Venation obscure, but more regular than in Californica. Female segment 

 slightly produced on median third. Male plates triangular, with the apices 

 attenuately produced. 



Colour : Vertex, face and pronotum pale buff, finely and evenly 

 irrorate with brown. Elytra powdery-white in fresh specimens, brownish- 

 white in older ones. 



Described from three females and three males from Williams, Ariz. 

 Collected by Barber and Schwarz, and received from the U. S. National 

 Museum. 



Koebelia coronata, n. sp. — Resembling irrorata, but with a still longer 

 vertex. Length, ?, 7 mm.; ^ , 5 mm. 



Vertex rather narrow and angled almost from the eyes to the round- 

 ingly pointed apex in the female, parallel beyond the eyes, and then 

 angled in the male. Elytra very short in the female, exposing the last 

 abdominal segment, as well as the long pygofers and ovipositor, as long as 

 the body in the male. Venation weak and obscure. Female segment 

 short, with the posterior margin slightly produced ; male plates long, 

 triangular, their apices not produced. 



Colour : Female pale ferruginous, male ferruginous-brown. A median 

 line on vertex and pronotum and a crescent just back of the apex of 

 vertex, light, more strongly marked in the male. Face ferruginous-brown, 

 a light line from the eyes along the carina? to the ocelli, then across in 

 about the curve of the vertex margin, except that it is strongly broken 

 forward in the middle. 



Described from a single pair from California in the collection of the 

 author. 



Koebelia grossa, n. sp. — Resembling irrorata, but larger and with a 

 more nearly quadrangular vertex. Length, $ , 6.5 mm.
