THE CANADIAN ENTOMOLOGIST. 313 



the anterior band crossing the cross-nervure between the sectors. Male 

 brownish fuscous, the face light, often with a pair of spots on vertex. 

 The submarginal spots on pronotum are united into a median crescent, 

 and the elytra are brownish fuscous, with two broad light bands. 



Described from twenty-four specimens from Fort Collins and Buena 

 Vista, Colo. This form has been (infused many times with alternatus 

 and its allies, but the short ovipositor and the bright rufous pygofers in 

 the female and the broad plates and simple antennae in the male 

 will readily distinguish it. 



/diocerus amoenus, var. depidus, n. var. 



Size and form of the species neatly, female ovipositor longer and 

 narrower. Male antennal plates slightly smaller. 



Colour : female rich creamy yellow ; eyes rufous ; pronotum, 

 scutellum and narrow scuteliar margin to elytra testaceous brown, 

 the colour deepening as you pass back from the vertex, a trace of 

 testaceous on the sutural margin before the apex of clavus. Male 

 pale creamy yellow ; basal angles of scutellum, scuteliar margins of 

 elytra, a spot before apex of clavus and the apical nervines testaceous. 

 Whole apex of elytra smoky. 



Described from two females and one male from Alameda Co., Calif. 

 Collected by E. M. Ehrhorn. This neat little form is remarkably distinct 

 in colour, but the structural characters are not of sufficient value to 

 separate it from amoenus on the small amount of material on hand.
