73. Idoemea calif ornica, sp. nov. 



Slender, cylindrical, brownish testaceous, pubescent; thighs a little 

 paler at base. Head wider than the thorax, eyes broadly contiguous on 

 the vertex. Antennae slightly longer than the body in the female, nearly 

 twice as long as the body in the male, clothed externally with rather dense, 

 very short, erect hairs, which become sparser and longer toward the base. 

 Prothorax cylindrical, a little dilated at the middle; surface finely, closely, 

 but somewhat unevenly punctate. Elytra about three-fourths wider than 

 the prothorax, gradually feebly narrowed behind, closely and a little more 

 -coarsely punctate than the thorax. 



Length, 13-16 mm. 



Beaten from live-oak, and taken at electric light at 

 Pomona and Pasadena, during April and June. There 

 is a specimen from Yuba County in the Horn Collection. 



/. californica is very similar to I. fulleri in a general 

 way, but the latter is somewhat stouter and more coarsely 

 punctured, the eyes are well separated on the vertex, 

 and the antennae in the male are described as being but 

 little longer than the body. 



74. Eusattus difficilis Lee. 



This species was based upon a series, part of which 

 was taken at San Diego and part at Vallecito. An ex- 

 amination of the Le Conte material shows that two 

 species were confused under this name. The San Diego 

 specimens, which may be considered the true E. diffic- 

 ilis, differ from every other species known to me in 

 possessing a well developed scutellurn. The Vallecito 

 specimens are apparently identical with a species which 

 was described by Le Conte as E. convexus, his type com- 

 ing from near Long's Peak, Colorado. This species he 

 describes as closely resembling E. difficilis, and subse- 

 quently it was placed in synonymy. E. convexus is a 

 rather common species, occurring from El Paso, Texas, 

 westward to the desert regions of California, while
