In a long series examined in this study, few constant differences 
separating the proxima-minnesotana series have been found, other than 
the secondary sexual characters stated below. The punctation and colour, 
truncation of the elytral apices, pubescence, angulation of the pronotum, 
all vary; but proximo is strongly angulate at the sides of the pronotum, 
whereas minnesotana is rounded. The males and females may be easily 
distinguished by the following characters : 
a. Females, with the last dorsal sclerite strongly carinate along the 
median line on the apical fourth, proximo Bay. 
b. Females, with the median area of the last dorsal broadly convex 
towards the apex, but at most only feebly carinate, minnesotana Csy. 
с. Males, with the last ventral very deeply, triangularly cleft at the 
apex, proximo Say. 
d. Males, with the last ventral flattened and subsulcate towards the 
apex, minnesotana Csy. 
The females of both series, a and b, have the last ventral segment 
variably sulcate. 
It is not possible now to decide which of these forms Mr. Say had 
before him when he described proximo. Col. Casey has described the male 
( c ) with the last ventral deeply cleft as proximo Say and this should be 
accepted as fixing the species. A . minnesotana Csy. was described from 
a male (d) with the last ventral uncleft. The relation of the sexes has been 
established by the writers through the collection of pairs. 
In the type series of minnesotana there are two males from Wisconsin, 
with the last ventral uncleft, followed by two males and eight females from 
Marquette, Michigan. The females have the carina on the last dorsal 
segment only faintly and broadly suggested. The single type of kempiana 
Csy. is a large female with all the characters of proximo , except that the 
pygidial carina is horn-like apically. It may prove to be distinct. 
A . subpubescens Kby. cannot be placed from the description in any of 
these four variations and is left under proximo Say. 
Seventy specimens had been examined before the relation of the sexes 
was discovered, from New York, Massachusetts, Maine, Northern Illinois, 
Ontario, Quebec, Manitoba, British Columbia, and Kansas. Other locali- 
ties cited in literature: New" Hampshire, Virginia, Georgia, Montana, 
Wisconsin, and Pennsylvania. 
Host plants: Acer (Felt), Acer , Hicoria, Castanea , Tilia (Craighead). 
Type locality: proximo, Missouri. 
Type locality: minnesotana, Wisconsin (Bayfield).
