 Caloptenux jilnmlniix 1)(ii)(4K, Can. Ent., IX, 1877, p. 12. 



Seventeen males, nine females, Denver July 1(5. 



The elytra of some spechnens are almost fuscous and distinctly 

 maculate, and the general color varies from fuscous to tiavous. But the 

 Havous stripe on a darker background is constant, and specimens of 

 this species can ])e separated ivom. fetHur-ruhruut with considerable 

 certainty l)y that chara(;ter and the general appearance. But those two 

 species are very close and may prove to be forms of the same thing,

Two females, Victoria, Texas, in June, 11H)2. These specimens are 

 typical in having the fuscous stripe of the lateral lobes of the pronotum 

 abruptly terminated at the posterior sulcus. Specimens of this species 

 taken in numbers at Rosslyn, Virginia, usually have this stripe per- 

 current, though ])ehind the posterior sulcus it is not generall}^ so well 

 defined.

Three females Avere taken in the vicinity of Victoria, Texas, in the 

 lattvi- paii of June, 1902. They were all flying in open prairies, and 

 other specimens were seen but not taken. They do not usually take 

 long flights, generally no more than 50 or 1<»0 yards. There is some 

 variation in the radial branches of the elytra, the inultlramom of 

 Bruiuier representing such variation.
