ish,’’ we should read “ anterior % 9 and posterior 9 femora partly yel¬ 
lowish.” 
Gr. GRASLINELLUS Walsh. For the sake of brevity I described this 
species by its differences from G. fraternus. Owing to the confusion 
already referred to as made by myself between conmhrhm^ n. sp., and 
fraternus Say, I unnecessarily stated that in 9 graslinellus there was 
no lateral thorn on the vertex. From the same cause I omitted to 
state that m graslinellus there are two uninterrupted blackish stripes on 
the thoracic pleura, viz., one on the suture behind the spiracle, and one 
half-way between that and the humeral suture, and also that the space 
between these two stripes, as in consohrinus n. sp., is livid not yellow. 
The hind femora are also shorter than those of fraternus in the pro¬ 
portion of 7 J to 10 i. e. one-fourth shorter. In describing the supe¬ 
rior abdominal appendages % graslinellus, by a clerical error I stated 
the large lateral tooth to be “quadrangular,” instead of “rectangular.” 
In its European representative, G. graslini, the lateral tooth is figured 
by Dr. Hagen as having its sides at an angle of about 50° or 60° to 
each other (^Mon. Gompli. Plate 8 , fig. 3.) So far as I recollect, the 
dorsum of the 9th and 10th abdominal segments varied in .its colora¬ 
tion as in fraternus, but vice versa, being generally marked above with 
yellow and only occasionally immaculate. The four specimens, how¬ 
ever, which I still have on hand, have each a simple, moderately wide, 
dorsal, yellow vitta on these two joints. I ought to have added also, 
that in % graslinellus the terminal abdominal joints are as much dila¬ 
ted as in S 9 fraternus, and that in 9 graslinellus they are scarcely 
dilated at all. As in fraternus 9 5 so in graslinellus 9 (3 specimens) 
the posterior femur is “anteriorly” vittate with yellow for l-f the way 
to its tip, whereas in both species the % posterior femur is immaculate, 
save that the knees are spotted with yellow above, as well as all the 
knees S 9 • allied G. vastus (6^,59) and in consohrinus 
n. sp. (3 S , 29 ),! find no trace of this singular sexual character. 
Another equally singular sexual character is found in the tarsal claws 
of consohrinus and externus and is noticed below. 
G. consohrinus n. sp. Yellow, very slightly tinged with green. Head with 
the occiput a little rounded above, but with the centre scarcely higher than the 
line of the eyes, fringed above with black hairs. All between the occiput and
