Kl ACKS: COLKOI'TERA OF" SoUTHWKS'IKRN PrNNSYI.VANI A. 281 



P. sp.? P. s]).? P. sp.? — Three other species distinct from the 

 foregoing, but near it, have occurred here in moderate nunil)ers ; I 

 have not as yet been able with satisfaction to identify them with 

 species hitherto described, and consider them new. 



Euplectus longicollis Cas. — This name has been given me by Capt. 

 Casey a few years ago for material sent to him for study. I have not, 

 however, been able to recognize the species among my numerous 

 captures of Ei/plccfiis, and record it on this list on the strength of the 

 name which was returned to me. 



E. confluens and E. elongatus are not scarce in western Pennsyl- 

 vania. 



E. new sp.? — A fine, hitherto undescribed species, very near elon- 

 Snafus, with which, diagnosed by the ventral marks of the males, it 

 forms a distinct group in the genus. It is larger than any other 

 Euplectus or Pycnoplcctus known to me ; two males and three females 

 have been found by sifting in the Loyalhanna Valley. 



E. iowaensis Cas. — As frecpiently met as confluens and elon:^atus, 

 and while distinguishable from them without great difficulty, I cannot 

 separate it from a series of iowaensis collected at Cedar Rapids, Iowa, 

 and given to me by Dr. Brendel under the name of E. confluens. 



E. pertenuis Cas. — A fine, small and abundant species, easily recog- 

 nized in both sexes by the cephalic peculiarities; it frec^uents rotten wood. 



Thesiastes fossulatus Brend. — A minute and very scarce insect in 

 this locality, found in decaying leaves, October 25, 1897. 



Bibloplectus rufipes Lee. — A still smaller species, which has been 

 but rarely found in decaying oak logs. 



B. leviceps Cas. — Besides the specimens from Cambria County re- 

 corded on the Hamilton List, a io-w have also been collected here ; 

 they are identical with a specimen in my collection, taken at Cedar 

 Rapids, Iowa, by Dr. Brendel, and kindly given to me. 



Entyphlus similis Lee. — Abundant, but only taken in the moun- 

 tains, and not in the immediate neighborhood of St. Vincent's. 

 Among a few hundred examples, only the males have been seen, these 

 coming from Cambria County (Rettger), and considered by Raffray 

 not to belong to the species similis. 



Thesium cavifrons Lee. — Sometimes taken in small numbers under 

 compost made up of weeds and grasses heaped up in corners of vege- 

 table gardens. My specimens were so found on February 27, 1S96 ; 

 others have also occurred since then.
