listed above were collected during a train stop in a most arid and 

 desolate location. 



Derotmema haydeni (Thomas). 



A series of five males and four females was taken at Williams, Sep- 

 tember 13 (two 6" , two 9 ), and Anita, September 11 (two c^, three ? ). 

 The disk of the wing is red in five specimens and yellow in four, regard- 

 less of locality. The series from Williams is more blackish than usual 

 in the species, while the Anita individuals are quite reddish. The 

 species has previously been recorded from Flagstaff. 



At Anita the species was common on reddish soil in an open field, 

 while at Williams it was taken in an open place heavily overgrown 

 with low vegetation. 



CONOZOA. Saussure. 

 Conozoa carinata Rehn. 



A series of five males and one female taken at Tucson, July 26, repre- 

 sent this species. These specimens are somewhat paler than the types, 

 while the males have the fastigium very slightly narrower than in the 

 female type. The female specimen has the metazona of the pronotum 

 abnormally humped, probably as the result of an injury. 



This species is now known to range from the Huachuca Mountains to 

 the Baboquivari range, north to Tucson. 

 Conozoa sulcifrons (Scudder). 



At Yuma this species was taken in numbers on July 26 and 27, a 

 series of twenty-one males and twenty-three females being secured. 

 When compared with a series from Grand Junction, Colorado, the 

 Yuma specimens are seen to average considerably larger. The Yuma 

 series is as a whole more warm brown in color, with the dorsal aspect 

 of the head, pronotum and anal field of the tegmina paler and more 

 uniform. 



The specimens from Florence and Phoenix, Arizona, referred to C. 

 acuminata with a query by the senior author^ belong to this species. In 

 size they are slightly smaller than Yuma individuals of the same sex. 



This was the most plentiful species found on the dry earth of the 

 river bed and along its banks. Although an active flyer no great 

 difficulty was experienced in capturing specimens. 



TRIMEROTROPIS StM. 

 Trimerotropis fascicula McNeill. 



A single female of this species was collected at light at Nogales, 

 August 13, 1906, by Dr. Calvert.
