(May) if specimens in my collection were properly iden- 

 tified by Casey. T. griseus, T. subcalvus, T. suturalis, and 

 T. politus have been announced from San Diego only: 

 fuscus occurs in San Diego County, and has been once 

 taken by me at Pomona (April 30): umbratus is com- 

 mon in cactus blossoms, at Palm Springs (April). A 

 large series taken by me makes it certain that fulvoves- 

 titus is the male of propinquus, and that both are syno- 

 nyms of umbratus. This species was described from 

 Fort Crook in northern California, and has been col- 

 lected in the Tempe Desert of Arizona by the late Dr. 

 Griffith of Philadelphia. T. su/usus, T. lobatus and T. 

 barbarce are described from Santa Barbara; specimens 

 taken by Mr. Daggett in Bear Valley (San Bernardino 

 Mountains), at an elevation of 6400 feet, are identi- 

 fied by Casey as his seriellus, described from Utah: 

 brevicornis is found at Pomona, Pasadena, Redondo, 

 etc., in spring, being especially common near the coast: 

 vilis is not different: conspersus is common at Pomona, 

 Riverside, San Diego, etc., March to May: squalidus, 

 sordidus and tejonicus are more or less common at San 

 Diego, Riverside, Pomona and Pasadena; they appear 

 to run into one another, and it is not unlikely that they 

 represent but a single species: crinifer occurs at River- 

 side (May): fulvescens, San Diego and Pomona: nigrinus, 

 Pomona and Pasadena: pedalis and punctipennis , Santa 

 Catalina Island, and cenescens, "San Diego and the 

 islands off Santa Barbara." The following are described 

 from Southern California without definite locality: com- 

 pactus, apicalis, testaceus, prominens, and cuspidatus; 

 insignis is from the southeastern region. Of the species 

 occurring in the State outside of our district, quadricol- 

 lis is from Fort Tejon; brevipilosus from the central 

 region; innocens from the middle Sierras; fraternus,
