Atlanticus calcaratus new species (PL VI, figs. 1, 19 and 25; pi. VII, figs. 

 9, IS and 27.) 



This interesting species is a development of the glaber type, 

 being much nearer to that form than to A. dorsalis. From 

 A. glaber the present species can be separated by the shorter pro- 

 notum, the truncate caudal margin of the disk of the same, 

 the deeper and shorter lateral lobes of the pronotum, which 

 also have an appreciable indentation at the sinus, the more 

 acute angles of the disto-dorsal abdominal segment, the less 

 exserted and shorter cerci of the male, the subfissate subgenital 

 plate of the same sex, the more robust limbs and the greatly 

 elongate medio-internal distal spur of the caudal tibiae. The 

 prosternal spines are lacking in the available material of calca- 

 ratus, but as these may be individual in their indication we have 

 refrained from giving this feature as diagnostic. 



" Blatchley's record of the young of A. pachymerus (A Nature Wooing, 

 p. 223, (1902)) may refer to this species. See also under A. dorsalis and 

 calcaratus. 



« Recorded by Scudder (Proc. Boston Soc. Xat. Hist., xix, p. S3, (1877)) 

 as Thxjreonotus dorsalis.
