Myriopoda of Dominica. 473 



I take this opportunity of stating that from an examination 

 of the types I am able to corroborate the view entertained by 

 Dr. Meinert concerning the specific identity of the following 

 forms '.—ahernans, Leach, Grmjii, comiiilanata^ multispinataj 

 Newport, Ann. & Mag. Nat. Hist. xiii. p. 98 (1844). 



Otostigma cormocephalinum^ sp. n. 



Shining, with almost metallic lustre. Tergites, sternites, 

 legs, and antennae olivaceous ; head-plate and maxillary feet 

 and sternite castaneous. 



Antennce short, scarcely as long as the head-plate and the 

 first two tergites, thicker at the base, composed of sixteen or 

 seventeen segments, of which the proximal six are bare, the 

 rest being densely hirsute. 



Head-ijlate sparsely but somewhat deeply punctured, its 

 posterior two thirds furnished with two conspicuous anteriorly 

 diverging sulci. 



Maxillary feet and sternite manifestly punctured, the latter 

 marked in front with two deep sulci which, arising close 

 together near the inner margins of the prosternal plates, extend 

 nearly to the hind margin of the sternite and break up into 

 branches which are arranged subsymmetrically upon the two 

 sides ; the anterior half of each of these sulci is united with that 

 of the opposite side by two transverse branches. Prosternal 

 plates well developed, widely separated, each being divided 

 in front into two teeth, the internal of which is larger and bi- 

 or tridenticulate. Basal tooth distinctly bidentate. 



The tergites, including the first, but with the exception of 

 the last, strongly bisulcate, with the exception of the first eight 

 or nine marginate, the first three feebly punctured, all of 

 them slightly rugose. 



Sternites, with the exception of the first and the last, 

 strongly bisulcate, all of them slightly rugose. 



Anal tergite with a conspicuous median longitudinal sulcus ; 

 anal sternite wide, with gently converging lateral margins, 

 rounded postero-lateral angles, and convex posterior margin ; 

 anal pieurites marked with remarkably large, interspersed with 

 smaller punctures; the superior and posterior margins not 

 punctured ; the posterior inferior angle not elongated into a 

 process of any kind, but simply armed with a small spine ; 

 there is a second small spine in or near the middle of the 

 posterior margin. 



Anal legs broken off.
