Plains) measures but 4^^ mm., the largest (same locality) 63^ mm. 

 The tegminal surface may be smooth and polished, or dull and 

 rastrate, the lineations varying from the regular complete lines 

 of the type to interrupted and confused markings, resembling 

 those of P. gillettei; the inner angle of the clavus, however, is never 

 bare of lineations. Pronotal lines 6-9, either entire or much 

 broken and confused. The index of pronotal width divided by 

 pronotal length ranges from 2.22 to 2.60 in the 9 , and 1.79 to 2.73 

 in the cf ; that of the head width divided by the interorbital width 

 ranges from 2.87 to 3.57 in the 9 and from 3.60 to 4.20 in the c^ ; 

 that of the head width div^ided by the head length from 2.07 to 2.60 in 

 the 9 and from 1.68 to 2.33 in the d^. In the male the palar pegs 

 are sometimes crowded into two rows at both ends of the series. 

 The absence of functional wings in both sexes in this genus cer- 

 tainly interferes with the rapid dispersal or mixing of individuals 

 from adjacent localities, and thus brings about a partial segrega- 

 tion which would preserve and intensify aberrant variations. 

 This possibly explains the very unusual range of variability above 

 described. 



ENTOMOLOGICAL MEETING IN CALIFORNIA, 1915. 



The Entomological Society of America has received an in- 

 vitation from the Panama-Pacific International Exposition to 

 hold a meeting in some Californian locality in the summer of 1915. 

 This gathering may be at either of the Universities or on the Ex- 

 position Grounds. It has received the enthusiastic support of 

 western entomologists. These latter have attended many eastern 

 meetings, and this is an excellent chance for us to return the com- 

 pliment. It ma\' be possible for a number to go out with a party, 

 stopping ofif at one or more interesting points en route. As chair- 

 man of a special committee to consider this matter and report at 

 the next meeting of the Association, the undersigned would wel- 

 come suggestions in regard to this meeting, and also expressions 

 relative to the support it would probably receive from eastern 

 entomologists.
