110 CALIFORNIA ACADEMY OF SCIENCES. 



decaying stumps; Pomona, Ojai Valley, March and April: 

 ater, a single specimen obtained in the San Bernardino 

 Mountains, under bark, in July: longicornis, Santa Ana 

 River (Le Conte); I have seen only the type: carboni- 

 color, a single specimen so referred was taken by sweep- 

 ing, in the foot-hills near Pomona, in June: dimidiatus, 

 this species under the name ajffinis, which was given by 

 Le Conte to a form which differs in no respect except in 

 the black portion of the elytra involving the apical third 

 instead of half, is reported from "Washington Territory 

 and Southern California;" I have found it in the Lake 

 Tahoe region, and its occurrence in the mountains 

 further south is not surprising. E. rhodopus is not rare 

 under bark of decaying logs, in northern part of the State 

 and Oregon: mcerens is also northern: melinus, phelpsii, 

 cordatus, behrensii, and apicatus are found in the middle 

 Sierras and extend their range more or less to the 

 north: horni and atripennis are given as Calif ornian, 

 but without indication of locality. There is little doubt 

 that in collections more than one species is now in- 

 cluded under the name apicatus, and it would not be sur- 

 prising if the Californian specimens now so called were 

 distinct. 



Elatrinus. E. anthrax, " California." A specimen in 

 Mr. Ulke's collections is without definite locality. 



Drasterius. D. livens, not very common; Yuma, San 

 Bernardino (Wright), Santa Monica: grandicollis and 

 degans are both reported from "California," and it is 

 not unlikely that both occur in the south. 



Megapenthes. M. tartareus, rare; a single example 

 taken near Pomona in June, by beating; several speci- 

 mens taken at Pasadena, in April, on thistle bloom 

 (Fenyes): turbulentus, Pomona, San Diego, Pasadena;
