Supplement to the Descriptions and Figures of the Aran- 



EiDES OF the United States. By the late Nicholas 



Marcellus Hentz. 



Some years since, Professor Hentz published in our Journal* an il- 

 lustrated monograph of the Araneldes of the United States. The 

 original drawings, with many appended notes, came by this means into 

 the possession of the Society. Finding that many of the drawings of 

 parts, and a few notes upon the structure and habits of this rather 

 neglected group had been omitted, I have carefully gleaned whatever 

 seemed to be of any importance, for publication in the Society's Pro- 

 ceedings as an appendix to his Monograph. 



A few of the original drawings engraved on the plates in our Journal 

 are unfortunately missing ; these are the ones figured on plates viii 

 and xvii of Vol. iv. Herpyllus duhius is stated in the text to be fig- 

 ured on plate xxiv, fig. 24 of Vol. v, but no such figure is there, and 

 no drawing of that species can be found. All the others are in the 

 Society's possession. 



It is worthy of remark in this connection, that the principal locali- 

 ties from Avhich Professor Hentz obtained his Araneides were North- 

 ampton, Mass., College Hill, N. C, and Tuscaloosa, Ala., and that 

 when " the United States " is given as the habitat of a species, it simply 

 means that he had specimens from Massachusetts, and from one of 

 the southern localities. S. H. Scudder. 



Katadysas pumilus. The nails of the cheliceres cannot be op- 

 posed to each other, but may perhaps nearly join at tip, as they may 

 in Miff/ale. Taken in January. 



Doloraedes albineus. Fig. 73, eyes. The area of the eyes is 

 black; thighs and breast all shining piceous underneath. Taken 

 July 3. 



Dolomedes lanceolatus. Specimens from Alabama are larger 

 than those from New England.

 and hairy, arranged 4, 2, 1, 3. Taken Feb. 28.
