Physocnemum violaceipenne Ham. — Of this species I know but 

 three specimens, all taken at Jeannette on oak. 



Elaphidion irroratum Fab. — Rare near Pittsburgh; unicolor not 

 rare on oak and hickory. 



Heterachthes ebenus Neivm. — A widely distributed species, but 

 rare here. 



Phyton pallidum Say. — Occasional specimens are found on young 

 black-oak. 



Neoclytus devastator Lap. — A simple example has occurred at 

 Jeannette. 



Cyrtophorus gibbulus Iaw — While classed as a synonym of J/(?^v'(9- 

 clytus gazellula, it was believed to be a distinct species by Dr. Hamilton. 



Tillomorpha geminata Hald. — I have found about twenty speci- 

 mens at Jeannette on hawthorn bushes. 



Bellamira scalaris var. — Two specimens were taken at Wilmerding, 

 Pa., which are entirely black. When compared with scalaris \\iG,y z.x& 

 somewhat smaller in average size than the males, but I can find no 

 other difference except in color. They are both males. 



Acmaeops thoracica Hald. — These can readily be separated from 

 bivittata by the deeply concave, depressed thorax. They are very 

 rare here. 



Cacoplia pullata Hald. — This rare insect is seldom found here. 



Liopus cinereus Lee — While but a variety of alpha, the form 

 should be listed ; commonly found. 



Lepturges var. pictus Lee. — Occasionally found on hickory. 



Hyperplatys var. nigrellus and femoralis. — Bred from the limbs 

 of chestnut trees. 



Grapisurus pusillus Kirby. — Rare at Jeannette and in Pittsburg. 



Acanthocinus obsoletus Oliv. and nodosus are both rare here. 



Hoplosia nubila Lee. — A number of these were taken at Charleroi 

 by Mr. O. Ehrmann. 



Pogonocherus mixtus Hald. and Eupogonius pubescens Lee. are 

 both rare here. 



Hippopsis lemniscata Fab. — Two specimens taken at electric light. 

 This species has a remarkable distribution. I have seen specimens 

 from almost all the Middle and Southern States, as well as from the 

 Atlantic States, and have specimens from Mexico, Costa Rica, and 

 Chapada in southwestern Brazil. 



Saperda obliqua Say. — This species has at last found its way hither ; 

 a few specimens were taken at several places in our region.
