General oolor of tegmenta brownish black irith metasonhci eingulate irith 

 light brown, the light band broadening below pore and sometimes below 

 embracing prosonite ai well as metaaonit* while doreatt} H nag be absent or 



iit only seross anterior region of metasonite, t be caudal portion remaining 

 blackish like the prosonite. Legi reddish brown or ferruginous. Collum 



bordered all around with light, otherwise shining black like the bead. 



Sulcus of head rather weak, interrupted briefly in frontal region dypeal 



foveolae 2 -+■ 2. 



Lateral striae of typical segments of median region rather coarse and deeply 

 impressed, well separated excepting ventrally, angled at suture and rising 

 obliquely both in front of and behind the latter but more so in front as usual. 

 Similar striae for a short distance above pore but this not crossing posterior 

 portion of metazonite. Suture distinct below and immediately above pore 

 but across dorsum passing into a shallow broader and less distinct furrow; 

 suture above pore in line with center of pore, curving closely about the latter- 

 above but only gradually resuming position below. Scobina very small, 

 ceasing at twenty third segment. 



Number of segments, fifty-five. 



Length, up to near 40 mm.; greatest width, 5.6 mm. 



594. DlNEMATOCRICUS AUKIANUS, sp. I10V. 



Type.— M. C. Z. 4,930. Paratypes .— M. C. Z. 4,931. Solo- 

 mons: Auki (W. M. Mann). 



Body olive-black, the color deeper along caudal border, anterior region of 

 covered part of prozonite lighter and a spot on each scobinum often yellow. 

 Legs light ferruginous. 



Sulcus of head distinct and complete though weaker and sometimes obscure 

 for a short distance in the frontal region. Clypeal setigerous foveolae 2-1-2. 

 Antennae when bent back along side reaching to fourth segment. 



Second tergite extending much below collum, the latter of usual general 

 form and not specially marked. 



Suture of segments complete though fine and not deep across dorsum. 

 Covered part of prozonite and anterior part of exposed portion dorsally with 

 a number of strong transverse striae of which the most posterior, taking its 

 origin well above the pore on each side, extends completely across dorsum, 

 this much coarser and deeper than the primary suture. On venter and lower 

 part of side of typical segment the striae are coarse and strongly marked, 

 horizontal across metazonite and curving dorsad of cephalad in front of suture; 

 the striae in front of suture continuous up to near pore but those caudad of 

 suture ceasing toward middle of side. Suture contiguous with pore, curving 

 about and embracing the dorsocaudal fourth of its circumference. Scobina 

 small, extending to the thirty fifth somite. Segments caudally obviously 

 bisinuate, the margin incurving over each scobinum of the succeeding segment.
