inner margin and minutely tuberculate. Cuticula finely tuberculate. 

 Large tubercles reticulate (fig. 226), bearing several long stiff yellow 

 setae. Maxinaum length, 5 mm. 



In the males, breadth is to length as 1: 2.27; in the females, as 

 1:1.79. 



This well-marked and monstrous species has been recorded from 

 several localities in Siberia by Tullberg, Shott, and Axelson; from 

 Ellesmere Land by Wahlgren; and was found by the Harriman 

 Expedition at St. Paul Island, Bermg Sea. 



NEANTIRA MAGNA MacGillivray. 

 Plate 23, figs. 229, 230. 

 Anoura magna MacGillivray, 1893a. 



"Body short, broad, one-half as broad as long, finely granulated. 

 Each segment with four dorsal and two lateral globular tubercles, 

 except the last, which is deeply divided, having as its apex two 

 immense globular tubercles. On the anterior part of the anterior 

 margin of each segment another smaller tubercle. From each 

 tubercle there arise from four to eight short, stiff, yellow bristles. 

 On the dorsal part of the head the number of tubercles is. the same, 

 but the two median tubercles are placed on the caudal portion of a 

 large quadrangular tubercle, which reaches from between the bases 

 of the antennae to the caudal part of the head. The ground color 

 is a light steel blue, with fighter spots between the darker tubercles. 

 Antennae very short, not reaching the lateral margin of the body by 

 at least a quarter of its width, segments subequal, indistinctly marked. 

 Eyes at the side of the base of the quadrangular tubercle, postantennal 

 organs wanting. Buccal orifice blunt, short, and white. Legs short, 

 with a single strong claw. Length, 5 mm. (0.20 inch). Habitat: 

 Sahneville, Ohio. 



"Tliis species can be recognized by its size, color, and the globular 

 tubercles; from gigantea TuUberg, its nearest ally, from Siberia, by the 

 absence of the postantennal organ." (^lacGiUivray.) 



The following notes, which I made from a cot}T)e given to me by 

 Doctor MacGillivray, wiU assist in the identification of this species. 

 Prothorax with eight segmental tubercles, equal in size. Mesothorax 

 and motathorax each with eight, of which two lateral tubercles are 

 posterior to the rest. First three abdominal segments each with 

 eight. Fourth" abdominal segment with eight visible from above 

 (fig. 229) ; an anterior row of six, and a postero-lateral tubercle on 

 each side. Genital segment in dorsal aspect with two large terminal 

 tubercles (fig. 229). Anal segment not visible from above. Unguis 

 (fig. 230) stout, curving, strongly unidentate one-third from the base 

 of the inner margin.
