130 ENTOMOLOGICAL NEWS. [May, '05 



punctate, carinate between the coxae. Hind femora finely alutaceous 

 and sparsely punctate over the entire surface. Spur of anterior tibiae 

 stout and strongly arcuate apically in the male, more slender and nearly 

 straight in the female ; basal joint of hind tarsus slightly longer than the 

 next three. Length 6-7X mni. 



Described from a good series of specimens communicated 

 by Dr. F. E. Blaisdell, who took them on November 24th from 

 a wood rat's nest in the Alhambra Valley, Contra Costo 

 County, California. 



This is the species referred to by Dr. Blaisdell in the report 

 of the proceedings of the fourteenth regular meeting of the 

 Pacific Coast Ent. Soc. as A cribrahis/^ The entire catch of 

 ninety-six specimens was taken " in a clump of earth at the 

 bottom of the nest, wet with excrementitious fluids, and no 

 larger than a double fist. The larvae also were taken." 



A careful comparison with the other members of Horn's 

 "Group G," to which the present species belongs, shows 

 that it is unquestionably distinct and differs from all of them 

 more than they do from each other. By Horn's table it would 

 fall with cribratus because of the simply emarginate clypeus, 

 but it differs from this, and nevadensis arid gentilis as well, by 

 the smooth front, more quadrate prothorax with better de- 

 fined hind angles and well marked exterior basal sinuation, 

 the alutaceous and more strongly numerously punctate hind 

 femora, and the longer basal joint of the hind tarsus, this 

 being subequal in length to the three following in gentilis and 

 cribratus, and distinctly shorter than the three following in 

 nevadensis. In the dual pronotal punctuation blaisdelli agrees 

 with nevadensis. It is not unlikely that the present species 

 may be found mixed with cribratus in collections; if so, the above 

 distinguishing characters will enable it to be readily separated. 



Aphodins knansii n. sp. 



Moderately elongate, slightly broader posteriorly, pale yellowish testa- 

 ceous, shining, disc of thorax irregularly nebulously infuscate, elytra 

 with a short fuscous stripe on the fifth interspace near the base, a common 

 transverse spot just before the middle reaching to the third stria, and 

 usually extending somewhat forward on the third interspace ; markings 

 frequently faint or nearly obsolete. Head without trace of tubercles,
