also indicates probable distinctness, for with the possible excep- 

 tion of Underivoodia iidoides (Harger) there is no chordeumid 

 species known from localities so widely separated.

Plate V, figures 79-94. 



Eyes triangular of about 19 ocelli, arranged in four rows, as in C. fiseheri, 

 2+4-1-6+7, though this formula is varied by the interposition of small ocelli, 

 and the curving of the rows. 



Antennee filiform, 3.5 mm. long, .16 mm. thick; ratio of lengths of joints 

 beginning with the seventh, 2.5: 4.5: 8: 7.5: 10: 4.5: 1. 



Gnathochilarium as in C. fisclieri. 



First segment semicircular or subreniform ; about half way from the median 

 line to the lateral angle is a well-pronounced depression about the size of the 

 base of an antenna; the middle tubercle is also situated in a smaller, more 

 shallow depression. Tubercles arranged as in C. fischeri. Surface nearly 

 smooth, a very fine median furrow beginning about the middle of the segment, 

 and extending to the posterior margin. Anterior mai-gin raised. 



Subsequent segments nearly the same as in C. fischeri. The ridge of the 

 dorsal furrow is somewhat fainter, and the oblique wrinkles of the posterior 

 portion of the segment do not appear. Moreover the whole dorsal surface of 

 the segments is very minutely hispid with microscopic point-like bristles, 

 either not present or scarce in C. fischeri. Posterior setae as long as the seg- 

 ments. 



Anal segment without median furrow or ridge, truncate behind for a dis- 

 tance of about half the breadth of the segment, the eight setse arranged as in 

 C. fischeri, except that the outside pair are farther away from those above them 

 than in that species. Surface more finely areolate punctate than the other seg- 

 ments and with the microscopic point-like hairs. 



Anal valves not strongly convex, more prominent above the middle, and 

 almost angulate, with three setigerous tubercles along the margin somewhat 

 more prominent than in C fischeri. The surface of the valves is like that of 

 he anal segment. 



Preanal scale as in C. fischeri. 



Color uniform light horn-brown. 



Length 17 mm. ; width 1.7 mm.
