ARTICLE VIII.—BRIEF MISCELLANEOUS NOTES. 
1. Black Locust. 
(Nematus robinice, n. s.) 
(Plate XII. Fig. 5.) 
From a number of saw fly larvae found infesting the black lo 
(.Robinia pseudacacia) at Normal, we bred during the latter pai 
July a small saw fly related to Nematus bivittatus and aureope 
but apparently undescribed. 
Body stout, pale brownish yellow; mesothorax with a black 
upon each side; metathorax with a transverse black band contin 
with the posterior extremities of the mesothoracic stripes; ter 
blackish with the sides and posterior margins of the segmeni 
the general color; prothorax between the ends of the mesothoj 
stripes a little darker brown; head slightly darker than the l 
with a quadrate black spot upon the occiput, extending forwai 
include the ocelli. This area is slightly -shining, but the adja 
surfaces of the head are dull, punctured, and rather densely pi 
cent. Antennae longer than the head and body, third and fo 
joints equal; clypeus emarginate in front. The under parts and 
are uniform pale yellow brown, except the tibiae and tarsi of 
posterior pair which are dusky, and the genital valves of 
female, which are black. Wings hyaline, veins fuscous, costa 
stigmata yellowish, second submarginal cell slightly angled ai 
recurrent nervules, of which there are two about equally rem 
from the two extremities of the cell. First submarginal quad 
distinct; posterior margin of wing behind the lanceolate cell sli; 
tinged with yellowish. 
Length of body 4 mm.; expanse 10 mm. 
Described from a single female. 
The larva from which this specimen was bred entered the gr 
July 8, 'the imago emerging on the 26th. 
2. Onion. —At Champaign, July, 1883, my attention was c 
by Prof. Burrill, to some hairy larvae that were destroying onio 
his gardens, as far as their numbers enabled them. Although 
seemed to be the larva of Spilosoma virginica, Fab., its colors 
somewhat unusual, and we bred it for identification; but 
imagos proved to be unquestionably that species.
