2. LASPEYRESIA BRACTEATANA CORNUTANA (Dyar) 



(Fig. 151) 



Epinotia cornutana Dyab, Proc. Ent. Soc. Washington, vol. 5, 1903, p. 231. 

 Enarmonia cornutana Baknes and McDuNNOxioH, Check List Lepid. Bor. 

 Amer., no. 7166, 1917. 



The only specimen of this I have seen is the female type. It has 

 nothing to separate it from hracteatana except its larger size and 

 darker banding (somewhat heavier chitinization) of the abdominal 

 segments, a character not visible until the abdomen is completely 

 denuded. For the present the name should be retained. It probably 

 designates a good food plant or local race. 



Genitalia figured from type. 



Alar expanse. — 17 mm. 



Type. — In National Collection. 



Type locality. — Williams, Ariz. 



3. LASPEYRESIA LARICANA (Bnsck) 



(Figs. 155, 317) 



Laspeyresia laricana Busck, Proc. Ent. Soc. Washington, vol. 18, 1916, p. 

 152. — Baknes and McDunnough, Check List Lepid. Bor. Amer., no. 

 7251-1, 1917. 



This and the following two species are cambium miners in the 

 bark of coniferous trees. They are very similar and possibly only 

 food plant races of a single variable species. Further rearing will 

 be necessary to determine this. The pattern differences are shown 

 in the figures. The female of laricana has the genital opening larger 

 and the genital plate more strongly chitinized than those of the 

 others. The male has the aedoeagus quite stout, straight, and not 

 perceptibly tapered; the cornuti are arranged in three clusters of 

 stout fixed spines, some very short and some moderately long. 



Hind wing with veins 3 and 4 connate or stalked. 



Genitalia figured from specimens in the National Collection from 

 Missoula (male, reared under Hopk. U. S. No. 11551, May, 1913, 

 from larva in cambium of Douglas fir, J. C. Brunner, collector) and 

 Evaro, Montana (female type, reared under Hopk. U. S. no. 12330, 

 May 5, 1914).
