Aphoromma granaria I\IacGili,ivray, 18936. — ^W'illem, 1902. — Guthrie, 1903. — 

 Wahlgren, 1906a. 



Wliite. Buccal cone short. Eyes absent. Postantennal organs 

 (figs. 212, 213) with 12 to 21 elliptical to ovate peripheral tubercles 

 arranged in a rosette. Antennae shorter than the head, stout, conical, 

 with segments subequal in length; fourth segment with eight short, 

 stout, olfactory hairs. Abdomen scarcely dilated. Unguis (fig. 214) 

 untoothed. No knobbed tenent hairs. Clothing of sparse minute 

 curving setae and occasional longer setae, the latter most numerous 

 on the head and the posterior part of the abdomen. Cuticular tuber- 

 cles large. Maximum length, 1.8 mm. 



My specimens of this species, collected in Neponset, Massachusetts, 

 November 20, agree with a single European example that I received 

 from Doctor Schaffer. 



This species occurs in such diverse situations as these: on the 

 seashore under stones and wood; inland under stones, under loose 

 bark, and in humus; in caves. 



Anurida granaria is widely distributed in Europe and is weU known 

 from the Arctic region, having been recorded from Siberia, Franz 

 Josef Land, Spitzbergen, Jan Mayen Land, and Greenland.

 small; supra-anal lobe semicircular. Segmental tubercles absent. 

 Eyes three or two on each side, or absent (in the known species). 

 Postantennal organs absent. Antennae conical, four-segmented; 

 fourth segment with terminal sense-tubercles and with olfactory 

 hairs; third segment with a pair of sense-papillae and two guard setae. 

 Mouth-parts piercing-suctorial, projecting forward in a short sharp 

 conical tube; mandibles without a molar surface, and with three or 

 more incisive teeth; maxillae and paraglossae apically styliform.
