188 NEUROPTERA. 
- The pair from Samana, Hayti, are the largest of the present material, a male from 
Atoyac the smallest, but all the West-Indian examples are not larger than those 
from Mexico.

(MZ. C. Z.) in Hayti? (R. J. Crew, coll. C. C. Adams: 1 3), San Domingo (coll.

The Mexican specimens were taken in February (Teapa) and June (Altamira). 
Mention is made on p. 182 of a slight colour-difference which they present. 
Prof. Brauer’s detailed description’ of . macromia agrees so perfectly with the 
Samana male placed by Hagen in the M. C. Z. collection as adnexa, and with 
Mr. Crew’s Haytian male identified as adnexa by Mr. C. OC. Adams after a comparison 
with Hagen’s type, that I have no doubt as to the specific identity of these two 
nominal species. Hagen’s failure to recognize this identity in 18675 was doubtless 
due to the mutilated ! condition of his type. | 
10. Aishna perrensi. (Tab. VIII. figg. 26, 27.) 
“lischna perrenst, McLachlan, Ent. Monthly Mag. xxiv. p. 76 (1887) }. 
Aischna rufina, Hagen, Proc. Bost. Soc. Nat. Hist. xviii. p. 88 (1875)? (no description ; quotes 
44. erythroneura, Selys MS., as a synonym). 
The two Mexican males have the pterostigma shorter (4 mm.) than in the unique type or the Paraguayan 
males (4:5-5°5 mm.), and the superior appendages are very slightly longer and wider than in those from 
South America, One of the Mexican specimens has a small subbasal inferior tubercle on the superior 
appendages, in the other (the one we have figured) this tubercle is rudimentary; in most of the South- 
American material before me this tubercle is entirely absent, but a rudiment is present in three of the 
Paraguayan males, placed a trifle more posteriorly than in the Mexican examples. 
The female of this species (not hitherto described) is coloured as is the male; the appendages of all four of 
the present specimens are broken.
