afford a fruitful field for some unbiased student. |

Loxa sp.? 
The Bolter Collection contains two examples of a species of Loxa 
labeled ‘‘N. Ill.” The genus has hitherto been known only from N. Mex. 
and Tex. (Uhl.) and Fla. (Van Duzee).

Of this uncommon species we have several examples from northern 
Illinois in June. Its recorded range is from Massachusetts to lowa and 
north into Canada. Banks has taken it on Ceanothus. 
ACROSTERNUM HILARE Say 
Pentatoma hilaris Say, N. Sp. N. Am. Ins. found by Joseph Barabino, 
chiefly in La., p. 9, 1832; Compl. Writ. Ent. N. A., Vol. 1, p. 304. 
This very common large green species is in our collection from 
numerous localities in the various sections of the state. It ranges from 
Canada to Brazil, and from the Atlantic coast to the Pacific. The Bolter 
Collection contains specimens from California, from which it had not 
previously been reported. The life history is very evident from the data 
at hand. The imagines are most frequently taken in May and the early 
part of June; there are only a few dates in July and August, but they 
become more frequent in the latter part of September, with records for 
October and November. The nymphal records are all for July and 
August and the early part of September. A number of food plants, trees 
and herbs, are recorded. Our data show the occurrence of the nymph 
on grape and ash, and of the adult on catalpa and apple. ,

[There appears to be some uncertainty as to the identity of the 
species in this genus, and an examination of types appears to me neces- 
sary to definitely decide the matter. I have figured one side of the male 
hypopygium in calva, dimidiata, and imbuta Walker—a Texan species— 
(Pl. XVIII, Fig. 25, 26, 27), to facilitate identification of the species dealt 
with in this paper. |
