H. C. FALL 343 



Distribulion . — Widely diffused in California. The 1yi)e locality is San 

 Bernardino Mts. Bowditeh also gives Independence. The following locali- 

 ties are represented before me: San Bernardino Mts., 5000 ft., July 12; 

 Los Gatos (Hubbard & Schwarz); Santa Cruz Mts. (Xut. Mus. Coll.); Santa 

 Cruz, June (Nunenmacher) ; Vine Hill, Contra Costa Co., June 7 (Blaisdell); 

 Burlingame, San Mateo Co., July 10; Fairfax, Marin Co., July 2, and Sabre 

 Vista, Sonoma Co., July 11 (Van Dyke); Bartlett Springs, June (Fenyes); 

 Yreka (Am. Ent. Soc. Coll.); Santa Catalina Island, July 30 :iiid Aug. 21. 



Yav. shasta Bowditeh 



The type of thi.s supposed species repr(>seiUs only an extreme 

 form of pundatus, in which the elytral spots are well developed. 

 I have precisely similar specimens from northern CaHfornia and 

 these are connected gradually with typical piinctatu.'s in my own 

 collection, and seemingly in Bowditch's collection judging from 

 his description, although he did not recognize the relationship. 

 He mentions only females in his description, and in my experi- 

 ence it is only in this sex that the spots are completely developed. 

 In the most conspicuously marked examples the rear spots 

 coalesce into an irregular transverse band, and also unite with 

 the middle interior spot. 



Specimens are known to me from Castle Crag (type locality — 

 coll. by Fen^'es) ; McCloud, June (Fenyes); Marin Co. (Van 

 Dyke's and my own collection). 



Aside from the rather extreme variation in markings from 

 immaculate in some pinidatus to completely maculate in t3-pical 

 shasta, this species is also more variable than usual in some other 

 respects, more especially in the width of the front between the 

 eyes, and in the punctuation at the sides of the elytra. Bow- 

 ditch describes this from one male and seven females. I have seen 

 the single male, which is marked "type," but have seen none of 

 the females of the type series; I have, however, before me a female 

 from the type region — San Bernardino Mts. — labeled }))indati(s 

 in Bowditch's handwriting and upon it I am depending largely 

 for ni}^ conception of the species. P)(ndatu-s is very closely 

 allied to both arizonensis and inarginijjennis; indeed I have seen 

 an example of the latter labeled pundatus by Bowditeh; as yet, 

 however, I have seen no indication whatever of elytral markings 

 in either arizonensis or marginipennis and the tabular characters 

 may perhaps prove to be quite reliable.
