198 THE CANADIAN ENTOMOLOGIST. 



rather narrow and almost parallel margined until just before the apex. 

 Elytra moderately long, appressed behind, costal margin curved, giving 

 the insect a stout appearance. Venation regular, often an extra veinlet or 

 two on the claval area, the third apical cell somewhat narrowed. 



Colour. — Vertex creamy yellow, a pair of round black spots 

 between the ocelli as in Sc/iwarizi, another pair just outside and posterior 

 to the ocelli, and a third and smaller pair equidistant from each other and 

 the eyes at the base. Sometimes some brown markings midway between 

 these and the apical pair assume the appearance of a pair of spots. Face 

 creamy, the sutures and arcs on lower part of front, smoky brown- 

 Pronotum cinereous, a row of submarginal dots set off by an arcuated line 

 and some irregular raottlings on disc fuscous or brown. Scutellum 

 creamy yellow, a pair of angular spots just inside the basal angles, the 

 impressed line and a pair of round dots on anterior disc black. Elytra 

 cinereous, shading to subhyaline on the margin, the nervures light, a 

 narrow dark, smoky stripe in the cells between the claval nervures and 

 another wider one just inside the outer sector of the corium, ending in the 

 third apical cell. 



Genitalia. — Female segment twice wider than long, the lateral angles 

 rounding, the posterior margin triangularly emarginate, one-third the 

 depth of the segment, with a strap-shaped tooth in the centre of the 

 emargination as long as the segmei.t. Male valve short, rounding, plates 

 together, rounding at base, then narrowly attenuately pointed and up- 

 turned. 



Described from ten examples from Tia Juana, San Diego and Salinas, 

 California, collected by the author. This distinct little group of the genus 

 already contains the names of Heidemann, who has made many eastern 

 forms known ; of Osborn, who has done so much in the Mississippi 

 Valley ; of Schwartz, for the intermountain region ; of Coquillelt, to whom 

 we owe much of our knowledge of the Coast fauna, and it seems but 

 fitting that we should add the name of Kirkaldy, who has done an 

 immense amount of work on our Pacific Island fauna and whose recent 

 untimely death is mourned by all.
