A NEW TEXAN PARAJULUS. 

 BY RALPH V. CHAMBERLIN. 



In a collection of diplopods sent to me for identification by 

 Mr. John J. Davis of the U. S. Entomological Laboratory at 

 LaFayette, Ind., was a specimen of an undescribed species of 

 Parajulus taken by J. D. Mitchell at Victoria, Texas, on Nov. 

 30, 1915, and reared to maturity at LaFayette, This form is 

 described below. 



Parajulus Iigifer, sp. nov. 



Male. — Body in general brown; a row of black spots over the repug- 

 natorial glands along each side and a middorsal longitudinal black line; 

 above level of the pores each segment is brown over the telescoped portion, 

 darker elsewhere, the darker portion geminate transversely and irregularly 

 by a light band. Anal scutum and valves blackish. Antennae blackish. 

 Head dusky above, pale below level of eyes. Vertigial sulcus obscure or 

 absent; a curved sulcus from the inner angle of each eye to a setigerous 

 foveola and the two foveolae connected by a sulcus or furrow slightly 

 curved dorsad. Eye-patch sub triangular with the dorsal angle acute and 

 the others obtuse; sides convex. Ocelli in nine transverse series; e. g., 12, 

 11, 10, 10, 9, 8, 7, 6, 5, a total of seventy-eight. First dorsal plate long, 

 lower margin straight; deeply margined below but with no other distinct 

 sulci or striae other than the margining one on each side. Second and suc- 

 ceeding segments deeply longitudinally striate below. No longitudinal 

 stria at level of pore. Repugnatorial pore moderately large ; in line with the 

 deeply impressed segmental suture which is strongly curved about it. 

 Anal tergite with tip acute, straight, and much exceeding the valves. Inner 

 border of the latter not at all raised, transversely striate. Mandibular 

 stipes not excavated, strongly angularly produced ventrad, the lower angle 

 almost attaining the level of the labral margin of head. First legs strongly 

 enlarged as usual ; the penult article long and straight, not at all curved, the 

 inner face flat. Second coxae greatly enlarged in the usual way, produced 

 ventrad in a linguiform process which is straight, narrowed gradually 

 distad but with the distal angles slightly flaring. In the general character
