Through the kindness of Prof. Dr. O. Taschenberg of Halle, 

 Germany, I have received the loan of the types of some of 

 Suffrian's species, so that certain of his obscure forms can be 

 accurately determined, but larger series are needed to define 

 their limits. 



The species which figures in our collections as the light var- 

 iety of P. striatus Lee. = pallidipennis Suff. ; probably Le 

 Conte's name will remain for the so called black yar. as a dis- 

 tinct species. The name of bivittatus Say should be attached 

 to the species now commonly labelled viduatus Fab. The real 

 viduatus occurs sparingly in the southern states, is much larger 

 and stouter and has a very well marked M on the thorax. Mr. 

 Loding has sent me several from Alabama and I have it from 

 North Carolina and Georgia. Suffrian's description of vidu- 

 atus fits this species very well and does not fit bivittatus at all. 



Characteristicus Suff. is wholly grayish-white. I have typi- 

 cal specimens from Lake Worth, Fla., and New Jersey. It is 

 rather flattened in shape; the type $ has only one unbroken (by 

 punctures) elytral interspace running along the side from near 

 the humerus. My specimens exactly agree with it in that par- 

 ticular. . Query, as to the food plant? It is very close to 

 atomarius Mels. which lives on oak. 



Impurus Suff. is entirely rust colored with three darker spots 

 on the base of the thorax, and three more along the side and 

 two on the disk of each elytron. My specimens of this are 

 neither of them exactly typical. 



Peccans Suff. type is black and yellow, the former color 

 predominating and with a round yellow spot in middle of each 

 elytron. .My specimens are not exactly typical. They come 

 from Massachusetts and the Middle States. 



Spumarius Suff. type $ is still yellower than peccans and 

 has also a round spot on the elytra. I have one male ex- 

 ample from Tennessee which is the counterpart of the type. 

 Nothing is known of the habits or food plant of any of these 

 four Suffrian species. 



I note the occurrence of several Mexican forms from the 

 Southwest, among them laticollis Jac. from Brownsville.
