but the former has the tibiae acutely tridentate, while in arizonica they 

 are bidentate, with the second tooth very feeble and alike in the six 

 specimens (all males), which I have seen. The specimens, when 

 taken, were by no means old and worn, but were all fresh and looked 

 as if they had just emerged. Each of the two black thoracic marks in 

 fulveola is divided behind middle, while in arizonica they are entire, 

 but specimens of the former will undoubtedly occur in which they are 

 also entire. 



Euphoria leucographa var. rufina Gory & Perch.

I mention this species here as there seems to be a mistake made 

 somewhere. Professor Snow recently sent me a few specimens of what 

 I had considered to be the above species, under the name sKbtomeutosa 

 var. histrionella. In calling his attention to the possibly wrong identi- 

 fication, he wrote me that the species was identified for him by Mr. 

 Liebeck and that the species stands under that name in the Horn collec- 

 tion, which was also told me by Dr. Skinner. Mr. Blanchard,^ who 

 mentioned the occurrence of these two species in Arizona at the sug- 

 gestion of Dr. Horn and who undoubtedly had seen or received some 

 of Horn's specimens, gave a short description of each of these species, 

 but they do not agree with Dr. Horn's specimens as they now stand 

 in his collection. From Burmeister's descriptions f and Bates remarks, | 

 however, there is no doubt that Mr. Blanchard's description refers to ^ 

 the right species. Burmeister separates leucographa from rufina by the 

 blackish seneous color, clypeus deeply emarginate and the antennal 

 club nearly as long as the head ; the latter is said to be shorter than 1 

 the head in rufina, in which the clypeus is not emarginate and the color r, 

 cupreo- fuscous. The difference in the length of the antennal club ij 

 sexual, the emargination of the clypeus and the color are variable, 

 shown by Bates and which can be observed also in the Arizona speci 

 mens, where, however, the blackish seneous specimens do not seem to: 

 occur. The Arizona specimens are reddish, with slight aeneous tint, 

 thorax with more or less distinct, black, longitudinal marks on each 

 side of middle ; elytra similarly marked with white spots as in nielan- 

 cholica, the disk sometimes more or less blackish. From what I could
