he kindne: ss of Prof. Dr. O. Taschenberg of Halle, 
ETEEIIGA fhe loan of the types of some of 
S$ species, so that certain of his obscure forms can be 
accuratel; determined, but larger series are needed to define 
species which figures in Our collections as the light var- 
Tae P. siviatus Lec. ax pollidipennis Suft.; probably Le 
name will remain for the so called black var. as a dis- 
t species. The name of bivittatus Say should be attached 
fe “to { ties now commonly labelled widuatus Fab. The real 
eee $ occurs sparingly in the southern states, is much larger 
| ad stouter and has a very well marked M on the thorax. Mr. 
is Lad has sent me several from Alabama and I have it from 
Nor ‘Carolina and Georgia. Suffrian’s description of vidu- 
is fits this species very well and does not fit bivittatus at all. 
 Characteristicus Suff. is wholly grayish-white. I have typi- 
i iistinens from Lake Worth, Fa. and New Jersey. It is 
‘rather flattened in shape; the type ¢ has only one unbroken (by 
ve ) 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 
Mels. which lives on oak. 
is still yellower than peccans and 
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

I note the occurrence of several Mexican forms from the 
~ Southwest, among them Jaeticollis Jac. from Brownsville.
