Loding, that I had set aside as seemingly different from rohoris 

 though closely allied. In it the eyes are a little closer than in 

 typical rohoris, the prothoracic punctures do not cjuite reach the 

 side margins, leaving a narrow smooth marginal line, and the 

 elytral striae are more deeply impressed posteriorly than in 

 rohoris. These differences all characterize the Suffrian speci- 

 men, the smoother side margin of the prothorax being however 

 considerably wider than in the Tumbling Gap male. In the fe- 

 male of rohoris the prothorax is densely punctate to the extreme 

 margin, and the lateral marginal interspace of the elytra is wider 

 and more denseh' punctate throughout, and the eyes are sepa- 

 rated by from two and three-fourths to three times the length 

 of the basal antennal joint; a combination of characters which 

 readily separates it from the Suffrian spumarius. 



At this point it is necessary to state a fact which may perhaps 

 complicate the situation considerably. Six years ago, among 

 other Suffrian types sent to Mr. Bowditch for examination, was a 

 male of spumarius, concerning which, after a brief inspection, I 

 made the following comparative notes. "Seems nearly inter- 

 mediate between rarians and rohoris. The prothorax is less 

 strongly rounded at sides than in rohoris, but is nearly as in 

 varians: the thoracic markings are as in varians, the spots a little 

 larger however, but not so diffuse as in rohoris; the elytra are also 

 intermediate in sculpture, the marginal interspace well defined 

 and with punctures nearly throughout, but so narrow that there 

 is room only for a single series of punctures; elytral spots small 

 and rather more diffuse than in varians, but less diffuse than in 

 rohoris, except the anterior discal one, which is diffuse and shades 

 into the suture nearly as in rohoris: posterior spot of discal series 

 lacking. Eyes separated by one and one-half or one and three- 

 fifths times the length of the basal antennal joint; front claws 

 missing." 



This sketch — in which of course the name rohoris is now sup- 

 plied, the species being then known by a number ("82") — is 

 not entirely in harmony with the Suffrian female above described, 

 and while the differences may be individual, there is a distinct 

 possibility that the}' represent different species.
