1912] Chilopods and Diplopods 159 
Ultimate legs long, the penult and antepenult joints furrowed 
longitudinally on ventral surface. -Claw long and stout. 
Sterna with a distinct median longitudinal sulcus or furrow which is 
crossed at middle by a transverse furrow. Pores not detected. 
Last ventral plate very wide, strongly narrowed caudad. Caudal 
margin straight or a little incurved. (See Pl. XII, fig. 3). 
Anal pleure bearing a number of small pores which are all wholly 
covered by the last ventral plate. 
Anal pores not detected. 
Pairs of legs 73. 
Length 34 mm.; width 1 mm. 
Locality: San Geronimo, New Mexico, (Mrs. W. P. Cockerell 
and Miss Mary Cooper, coll.). 
CLASS DIPLOPODA. 
Family NANNOLENID. 
Genus Buwatia gen. nov. 
Ocelli none. 
Antenne clavate, the fifth and sixth articles thickest; third and 
fifth longest, nearly equal in length, the second and fourth next. 
Body decidedly narrowed caudad of head to sixth segment. 
Body iulus-like in form. Segments without carina, nearly smooth, 
not clothed with hair. All segments striate beneath; a deep sulcus 
across segment at level of pore. 
Claws of legs long and slender. 
Type: Buwatia monterea sp. nov. 
As but one specimen of the type species has been secured, 
dissection for fuller structural details has not as yet been 
attempted. The genus may be distinguished from Nannolene 
through the absence of ocelli. 
Buwatia monterea sp. nov. 
Dorsum brown; head and anterior part of first segment whitish 
brown; first and ultimate segments light brown; a series of small, 
largely obscure dark spots along each side, one at each pore. Legs 
and antennz pale. 
Body slender, nearly uniform in width for most of length but de- 
cidedly constricted from head and first segment to region of sixth 
segment. 
Head nearly smooth, weakly and very finely punctate; glabrous 
except for a few bristles on clypeal and labral region. A weak median 
longitudinal sulcus across vertex. A furrow or excavation from base 
of each antenna caudad to lower margin of first dorsal plate, the an- 
tenna bent back and lying in this furrow. 
Antenne rather short, strongly clavate; the seventh article short, 
its four sensory cones almost concealed in the terminal pit; clothing 
of hair becoming more and more dense distad, sparse proximad.
