ABT.7. CENTIPEDS OF CENTRAL AMERICA — CHAMBERLIN". 5 



The specimen from Honduras is referred with some doubt to this 

 species, as the anal legs are missing. It may possibly, instead, repre- 

 sent the form N. sulana, new species, described below.

10. NEWPORTIA MIMETICA, new species. 



This species is close to the Guatemalan N. stolli (Pocock). As in 

 that species, the head has paired longitudinal sulci extending from 

 the caudal margin forward to or a little beyond the middle; these 

 sulci not connected posteriorly by any transverse line. Cervical 

 sulcus evenly curved, in the types covered by the cephalic plate or 

 free only at the middle. Paired sulci of first plate parallel and un- 

 branched, extending forward in front of transverse sulcus. Paired 

 sulci extending across anterior third of second tergite, but complete 

 on the others to the twenty-second, inclusive. Last tergite without 

 a median sulcus. Prosternum with dental plates short and broad, 

 convex. Last tergite without a median sulcus. Tarsi undivided 

 excepting in last two pairs of legs. Tibiae of anterior legs armed 

 beneath at distal end but not laterally. Last ventral plate with sides 

 converging caudad, caudal margin mesally incurved, corners rounded. 

 Coxopleural processes nearly glabrous, lacking the pilosity on exter- 

 nal side present in N. stolli and N. sulana. Anal and penult legs 

 also with but very few hairs on mesal surface in contrast with the 

 condition in N. stolli. 



The general form of the anal legs as in N. stolli^ the tarsal division 

 similarly proportioned and without claw. Femur of anal legs flat- 

 tened within; lower edge typically with five distally curved teeth, 

 of which the two anterior ones are smaller ; upper edge with a num- 

 ber of points or spinules. and below them, on mesal surface, some 

 still more minute points or prickles. Differing from N. stolli in 

 having the two ventral teeth of the tibia situated one well behind 

 the middle and one in front of it instead of both being in front of it. 



Length, 15-19 mm.
