oiui t * r^i t « • extending below level of lower end ol solium, flattened below 

 Collum finely margined below and aboul anterolateral corner, not otherwise 

 striate, smooth. 



Striae ol metaaonitee on lower ndet sharply impreaaed, thoae of the j>n>- 

 aonitee more lightly impreaaed, eurving upward at anterior enda, especially 



the upper ones which occur farther dorsad than those of the nnta/.onite hut do 



not at tain the level of the pore. Tergjtefl oroaaed by two wit urei both of a Inch 



are distinct entirely across dorsum; the anterior one of theae takes its origin 

 near level of pore. Posterior margins of most scohiniferous termites with 

 posterior margins strongly sinuate over each seobinum of succeeding plate, 

 ibina extending from seventh to thirty seventh segments. 



Anal tergjte much exceeded by the valves. The latter strongly compressed, 

 their meaal borders elevated. 



In the gonopods of the male the anterior median plate has the median 

 distal tongue of a sublanceolate form, narrow proximally and with apex 

 narrowly rounded; the distal margin of basal part on each side is straight, at 

 right angles to axis of tongue but with ectal corner on each side rounded. 

 Telopodite of posterior pair with both branches very slender, the inner one 

 curving mesad and diverging from the other; the latter curving first gently 

 caudad of mesad and then more strongly caudad at tip. 



Number of segments, forty-seven or forty-eight. 



Length (male), 48 mm.; width, 4.2 mm. 



A species characterized by its peculiar coloration, which is brown to 

 reddish brown with caudal borders of somites darker, the color typi- 

 cally of a reddish cast; the legs of the male brick-red, those of the 

 female ordinarily paler and less reddish. The color in general often 

 suggests that of Trigoniulus lumbricinus. 



591. DlNEMATOCRICUS PATRUELIS, sp. nOV. 



Type.— M. C. Z. 4,925. Paratypes.— M. C. Z. 4,92G. Solo- 

 mons: Pamua (W. M. Mann). 



The entire body uniform shining black with legs ferruginous. 



Sulcus on head of male typically continuous though weaker in the frontal 

 and again in the upper clypeal region where in the female, at least, it is some- 

 times vague or absent. Clypeal foveolae 2+2. 



Collum as usual widely rounded and shortly weakly marginate below. 

 Second tergite extending much below collum, flattened beneath. 



Segmental suture absent or very vague in upper dorsal region on all somites, 

 distinct just above pore and down sides, curving closely about pore which is 

 in line with it. Scobina very broad but few in number, not extending caudad 

 of fourteenth segment. Above the scobina the margin of the preceding tergite 

 in each case obviously sinuate.
