Houotyre: Male, USNM 65406. 
Type Locauity: San Diego, Texas. Type collected May 18 (year 
unknown) by E. A. Schwarz. 
Paratyres: All from San Diego, Texas (USNM): 1 male and 1 
female, May 18 (E.A. Schwarz); 2 females, May 25 (E. A. Schwarz); 
1 female, May 18 ‘Coll. Chittenden’; 2 males and 1 female, May 18 
(Hubbard and Schwarz); 1 female, May 19 (Hubbard and Schwarz); 
1 female, May 16 (Hubbard and Schwarz). 
Brotoey: No host-plant data or other biological information on 
this species is presently available. 
Discussion: This species closely resembles S. lutulentus Dietz in 
regard to body shape, prothoracic punctation, shape of scales, and 
female genitalia. However, the white scales of the elytra are scat- 
tered, in the case of S. lutulentus, instead of being condensed into a 
median white patch, and the median lobe of the male genitalia of 
S. albonotatus is broader in proportion to its length and has larger 
orificial plates than that of S. lutulentus (compare figs. 67 and 68). 
In size, S. albonotatus seems consistenly the larger of the two species. 
The results of some F comparisons between S. albonotatus and 
S. lutulentus Dietz are given below; n=10 in male samples, 7 in 
female samples. A single asterisk indicates an F value significant 
at the 5 percent level, a double asterisk indicates an F value signi- 
ficant at the 1 percent level:
