segment to a line connecting the bases of tlie antennn', and diverge to 

 the auteiinal sockets, Tlie trianguhir space included is colored dark, 

 witli a median, longitudinally oval, light spot and a light spot between 

 the antenna". 



Clypeus subijuadrate, moderately convex, hirsute with rather short 

 hairs, rough(;ned medianly with fine, irregular, transverse Avrinkles, 

 latcially with very line granules; lateial edges nearly straight, sub- 

 parallel; lateral corners and lower median portion depressed and pro- 

 vided with a lew hairs. 



l"]yes located on posterior of vertex, close to the edge of the first seg- 

 ment, of irregular shape, composed of five ocelli of moderate size. They 

 are distant from the anteunai and are not close to the lateral margin of 

 the head. 



Antenna; located below the middle of the head and nearer to the 

 median line than to the lateral margin. When the animal is coiled up 

 the antenna- ar(; held with the first three Joints i)eri)endicu]ar, the 

 foiirth bent outward at a right angle to the third, the fifth is bent 

 downward at a right angle to the fourth, the sixth, seventh, and eighth 

 in a line with the fifth (fig. It) olfa(;tory cones with high bases, to which 

 tliey are articulated; that is, apparently two-Jointed. 



First segment very largy, more than twice as long as the exposed 

 l)ortion of the second segment, very rough with rough granules, and on 

 the posterior part of the dorsal portion with ten longitudinal carina', 

 well" pronounced, but not as large as those of the succeeding segments; 

 median carina; short, the lateral ones extending nearly across the seg- 

 ment; about one fifth of tlie s«;gment on each side is without carina-. 

 The i)osterior edge of the segment straight, and both tiie i)oste'rior and 

 anterior lateral corners rounded ; anterior i)ortion of segment inflated 

 and expanded so as to cover the head, the anteiior lateral corners 

 slightly produced ; anterior edge with a raised margin and slightly 

 curved, so that the lateral length is about two- thirds of the dorsal. 



Third segment footless, one pair of legs on the fourth segment, with 

 protuberances from tlie coxa; (fig. \<l). These legs are free; that is, not 

 joined to the body excei)t internally (the projections curve forward)^ 

 80 that this pair of feet could be protruded. 



yegm<;nts subsequent to the first with a small median carina, and 

 with six others, much larger, on each side, thicker and higher at their 

 posterior ends. Below these the surface of the segment is smooth for 

 a space about e(iual to three times the distance between two carina;, or 

 very finely roughened, but without the slightest trace of longitudinal 

 carina or striation. Jielow this is another carina, distant from the 

 ventral edge of the segment by somewhat more than the distance 

 between two dorsal carina;. This carina projects anteriorly from the 

 subsegment, and does not reach its posterior margin. The exposed 

 surface of the anterior subsegments and the posterior region of the 

 posterior are very rough with granules, and one or two more or less
