abundant species throughout the southern part of the 

 State; at Pomona, Pasadena and vicinity, it finds shelter 

 in cellars, and is, in fact, the only species of the genus 

 that occurs commonly about houses: pilosa and hirsuta 

 inhabit Owens Valley: scabripennis is known from Santa 

 Barbara and Santa Rosa islands and Fort Tejon; it 

 does not appear to be common: consobrina is not rare in 

 the foot-hills and up to altitudes of 5,000 to 6,000 feet in 

 the southern Sierras: tenebrosa occurs in Owens Valley: 

 parvicollis and its varieties, producta and marginata, are 

 given on the authority of Dr. Blaisdell, who names 

 them in a list of species observed by him in San Diego 

 County; both occur about San Francisco, and I have 

 never seen specimens from further south: subnitens has 

 been taken in San Diego County (fide Fuchs). The 

 following species occur in those parts of the State to the 

 north of our district: E. obscura var. sulcipennis> 

 desert region in the northeast; humeralis and elegans> 

 northern coast region; estriatus, davicornis and parvi- 

 collis, about San Francisco, the second named species 

 being very abundant in the sand-dunes on the ocean 

 front; dentipes, common to the south of San Francisco; 

 prominens, San Luis Obispo County; granulata, granosa 

 and cuneaticollis , exact locality not named, though it ia 

 probable that the first two occupy the desert region of 

 the northeast and possibly come as far south as Owens 

 Valley; cordata, middle region, from San Francisco to 

 Lake Tahoe, also ranging both north and south of this- 

 latitude in the central valley; scabricula, Sacramento 

 and Lake Tahoe. 



Embaphion. E. depressum, Vallecito (Le Conte). 

 Trogloderus. T.costatus, San Diego County (Fuchs). 



Eulabis. E. grossa is not rare on San Clemen te 

 Island, and has also been taken on Santa Barbara and
