well with Busck's (1910) description of leopardus from that city, as 

 well as with the type material representing leojpardiis in the U.S. 

 National Museum. A fourth series, five specimens from Pinal and 

 Pima Counties, Arizona, does not agree with the types of any of the 

 previously described species. This series, described below as a new 

 subspecies, heinrichi, agrees very closely with Dyar's (1903b) de- 

 scription of unistriganus from Coconino County, Arizona. How- 

 ever, Dyar's type material representing unistriganus has proved to 

 be laticajyitanu^, thus extending the range of the latter 6-700 miles 

 southeastward into north central Arizona. This places the type 

 locality of heinrichi about 350 miles southeast of that of occidens and 

 leopardus at San Diego, approximately 800 miles southeast of that of 

 laticapitanus in northern California, but only about 200 miles south of 

 the southernmost range known for laticapitanus . The fifth and last 

 series, consisting of five specimens from Cochise County, Arizona, 

 also does not agree with any previously described species. It is 

 described below as a new subspecies, clarkei. Cochise Co. borders 

 Pima Co. on the east and occupies the southeast corner of Arizona. 

 Thus, the type locality of clarkei is fairly near that of heinrichi. 



In aU the members of this complex the eyes are large, protruding, 

 devoid of setae and lashes, and offer no character for separation. The 

 labial palpi are short, upcurved, and \vith the basal segment the largest. 

 They are slightly longer in occidens and leopardus. The antennae are 

 simple vAih the segments stout and closely set together. Each seg- 

 ment is fm-nished with one complete ring of scales as well as a second 

 partial set on the dorsal surface giving each antenna a continuous, 

 overlapping, dorsal covering of scales from base to apex. In lati- 

 capitanus each antenna! segment bears two complete rings of scales, a 

 character consistently enabhng one to distinguish it from the other 

 members of the complex. In regard to size, occidens is generally the 

 largest of the gi'oup with a wing expanse ranging from 20 to 24 mm., 

 although one dwarf specimen of less than 18 mm. easily intergrades in 

 size with the other members. These are all quite small and range from 

 14 to 21 mm. in expanse. 



The color patterns of all the members are given with reasonable 

 accuracy and detail in the original descriptions (q.v.) and need no 

 further elaboration here. In la.ticapltanus, heinrichi, and clarkei 

 essentially the same, simple, consistent color pattern is exhibited. 

 In leopardus the color pattern tends to be slightly more complex and 

 variable. The occidens series exhibits the most complex and variable 

 coloration, and its wing pattern permits it to be separated into at 

 least two groups, the less frequent of which occurs in both Alpine and 

 San Diego, California. In general habitus, laticapitanus, heinrichi, 

 and clarkei resemble one another and are quite distinct from occidens
