Walsingham 's original description of laticapitanus follows: 



Pseudoconchylis laticapitana — Head whitish ochreous. Palpi the same, sprin- 

 kled with brownish scales externally. Antennae pale ochreous. Fore wings 

 whitish ochreous, mottled and speckled with ochreous greyish brown and brown 

 scales. Brown dots and spots are distributed around the costal and apical 

 margins, the extreme base of the costa being also brownish. There is an ill- 

 defined oblique fasciaform shade commencing below the outer third of the costal 

 margin, and terminating in an aggregation of brown scales on the fold; the brown 

 scales appear to be very fugitive, and in specimens only slightly worn are scarcely 

 noticeable. Hind wings and abdomen pale brownish. Expanse, 17 mm. 



Both sexes obtained in Lake County and Shasta County, California, June 

 25th to July 10th, 1871, by myself. 



Male genitalia identical with those of occidens, described below. 



Remarks. — The type material, including the holotype cf , is in the 

 British Museum (Natural History). Mr. Tams has sent me photo- 

 graphs labeled "laticapitanus Wals., type," which show an adult d^ 

 and its genitalia. Both of these agree with, a series of 33 cf cf received 

 on loan from the California Academy of Sciences. These were col- 

 lected by H. H. Keifer at Oroville, Butte Co., Calif., on the following
