MILLIPEDS OF ORDER COLOBOGNATHA — LOOMIS 367 



previous records of B. lecontei from there and from Arkansas (Boll- 

 man) in question. The Tennessee specimens may have been yetasata 

 and the Arkansas ones the same or even an undescribed species. 

 Considerable collecting must be done in these States to determine 

 what species occur, the old records no longer being reliable. 



BRACHYCYBE ROSEA Murray 



Brachycybe rosea Murray, Economic entomology, Aptera, p. 21, 1877,

 1880. 



Murray and Karsch gave only "California" as the locality for 

 their specimens. Those I have seen were collected at the Sunnyside 

 mine, near Seneca, Plumas County, Calif., by H. S. Barber in 1922, 

 and a description and photographs of this material appeared in 

 the paper hereinbefore referred to.* 



Drawings of the head and anterior segments of one of these speci- 

 mens are shown in figure 32, / and 57, for purposes of comparison 

 with drawings of other species. The gradual widening of the ante- 

 rior segments from in front is a character of the two Pacific coast 

 species, as is the rapid widening of the same segments characteristic 

 of the eastern species. 



BRACHYCYBE PRODUCTA, new species 



Two bottles in the National Museum collection contain specimens 

 labeled: (1) ^^Platydesmus, Lower Calif. Com. Dr. Marx"; (2) 

 "Calif. Acad. Sci. Com. Dr. Marx 10/93." The first bottle contains 

 one female, the other two males and three females. Although the 

 latter bottle is without locality data, the similarity of the females 

 to the one in the first bottle is unmistakable, and it is quite possible, 

 and indeed probable, that all specimens were collected at about the 

 same time and in the same place, which may have been in a wooded 

 section of the central mountainous portion of Lower California. If 

 the latter conjecture should prove true, it would not be unreasonable 

 to suppose that the species may .occur in some of the southern Cali- 

 fornia mountains. 



The type (U.S.N.M. milliped no. 1161) is a male. 



Diagnosis. — The principal differences between this species and 

 B. rosea are the longer body, the shape of the first segment, its 

 fewer rows of tubercles, the interrupted posterior margin of the 

 median segments, and the abbreviated posterior row of tubercles 

 on these segments. 



Description. — Body longer and slenderer than any other species 

 and slightly more convex. The largest specimen, a female, is 38
