1910] Diplopoda from the Western States 235 



In the female the coxae of the second to eighteenth legs inclusive 

 and of the twentieth or, as appeared in one specimen, of the second 

 to nineteenth legs inclusive, bear on their caudo- ventral faces con- 

 spicuous, distally inflated, sub-fungifomi outgrowths; the processes 

 of the third legs, however, reduced to smaller, low convex elevations. 



Oviducts of female protruding as greatly elongated appendages or 

 ovipositors which when extended caudad reach the eighth segment 

 of the body; distal portion of processes enormously enlarged, bearing 

 very long stiff bristles; proximally glabrous; showing a tendency to 

 segment into articles; color white. 



Number of segments 49 to 53. 



Length 26 mm. Width 1..") mm. 



Locality— Stanford, Cal. (W. M. Mann). 



FAMILY CRASPEDOSOMIDAE. 



Conotyla deseretae sp. nov. 



Dorsum brown; a dark band of black or bluish black color along 

 each side immediately ventrad of the carinae, the band commonly 

 extending dorsad on the prozonites and sometimes, especially on the 

 posterior segments, forming thus a band entirely across the dorsum; 

 a median longitudinal dark band along dorsum, and this typically 

 geminated throughout its entire length by a narrow light line. Venter 

 and legs paler, light brown to yellowish. Head commonly a consider- 

 ably darker, more reddish, brown than that of the body. Antennae 

 deep brown to blackish. 



Head widely and shallowly depressed or furrowed transversely'' 

 between the eye patches. Evenly hirsute with short hairs. 



Lingual lamellae of gnathochilarium with sides sub-parallel for 

 most of length; their length, inclusive of processes, three times the 

 greatest width. Lingual stili conspicuous, their lateral teeth distinct. 

 Spatula large, distally broadly rounded. Stipites a little less than five 

 times as long as the greatest width. Mentum with greatest diameter 

 somewhat more than twice the greatest length; its anterior margin 

 widely rounded; as a whole sub-semicircular in shape. 



Eye patches triangular, thQ apex directed forward; ocelli 25, more 

 or less, arranged mostly in seven series (6, 5, 5, 4, 3, 2). 



Antennae long, of tvpical form and proportions; length 3.5 mm, 

 vSee PI. XXXI, fig. 8. ' 



Body strongly narrowed caudad and cephalad, the first segment 

 constricted in the usual way; a sharp, low, median keel extending 

 along dorsum for its entire length, a narrow furrow impressed each side 

 of the keel. Second segment short, the inner bristles relatively farther 

 laterad than on the first, and these bristles located more and more dis- 

 tantly from the median line on subsequent segments back to the mid- 

 dle region of body. The lateral bristles, as usual, becoming directed 

 more and more strongly caudad in proceeding from anterior segments 

 posteriorly. Inter-segments or prozonal divisions in part encircled 

 by a series of fine transverse impressed lines, the elevations between 

 these crossed with fine striations.
