of the prehensorial legs and other strong similarities leave little doubt 

 that this is a member of the genus Escaryus, as was conjectured when 

 that genus was erected. 3 The anal legs were also strongly curved under 

 as has been the case with all the specimens of Escaryus yet observed. 

 That the differences enumerated between E. phyllophilus and E. urbieus 

 can be maintained, is doubtful, for the Cambridge specimen is in rather 

 poor condition, so that some of the characters ascribed by Dr. Meinert 

 may easily prove to have been accidental. 



Scolioplanes robustus Meinert. 



The locality of this species was not known. I have collected what 

 is evidently the same in central New York and southern Pennsylvania, 

 and am unable to separate it from Sager's Strigamia fulva, the probable 

 type of which I have seen in the Museum of the Academy of Natural 

 Sciences at Philadelphia. The only difference between it and bothrio- 

 pus and robustus seems to be that of size. The large specimens always 

 show evidences of good living. The creatures are also constructed so 

 as to be capable of considerable distention, besides being variable in 

 size and number of legs, even in the same localities. 

 Scolioplanes parviceps Meinert. 



The label in this bottle, probably in Meinert's handwriting is 

 "Scolioplanes parviceps n. sp." The bottle also contains a label 

 marked " Strigamia bidens Wood, N. A. loc. ? " It is evidently to this 

 label that Dr. Meinert refers when he says, (p. 226). " A specimen, 

 which was said to be a type of Dr. Wood, was labeled ' Strigamia bidens 

 Wood.' " To thus rename a type specimen seems a remarkable pro- 

 ceeding, especially when the new name proposed has already been used 

 in the same genus. Yet this is probably what Dr. Meinert proposed to 

 do, for Mr. Henshaw kindly showed me a list of the collection, care- 

 fully made out in Dr. Meinert's handwriting, and in this the species is 

 again given as new. That it did not so appear when the paper was 

 printed, may have been the work of some American editor who knew 

 of Wood's species and naturally supposed that the same was intended 

 by Meinert. 



Wood's parviceps is a Californian species, while bidens is found in 

 the East. I have collected it in the vicinity of Washington. I had a 

 specimen of parviceps at Cambridge with me to compare, but the differ- 

 ence was evident. There was no other specimen of bidens at hand, but 

 the size, form of the body and other characters agree well with the east-
