NEUROPTERA. 367 
At Jalapa and at San Pedro Sula the examples taken were associated with Argia 
oculata. 
Some Neuropterists may consider the Pacific Guatemalan specimens to be sufficiently 
distinct to receive a subspecific or racial name, but I think the transitions to the typical 
ulmeca, as indicated above, justify retaining all under the name here employed. I can 
find no structural differences.

3. The black humeral stripe is twice as wide as the pale antehumeral, in some. The black apical dorsal spot 
on abdominal segment 8 is broken into two spots in one male from Surubres, 
G (hitherto unknown). Differs from the male as follows: labrum black ; superior black stripe on each side 
of 2 wider, united with its fellow of the opposite side in basal and apical thirds, thereby leaving only a 
small elongate blue spot on the median dorsal third; mid-dorsal blue stripe on 3-6 narrower, reaching to 
two-thirds length of 3, half of 4, two-fifths of 5, one-fifth of 6; 8 and 9 each side with an inferior black 
stripe as long as the segments and a superior black stripe from base to two-thirds of 8, to half of 9, the 
two superiors confluent at base, and on 9 with the inferiors also at base ; 10 blue, sides inferiorly black.

@. None of the specimens of this sex previously referred to oculata were labelled as having been taken 
in coitu. The supplementary material includes nine pairs, the male in each case being undoubtedly 
oculata ; the females differ considerably from each other, and consequently give rise to several questions. 
The two females from Jalapa taken in coitu have the labrum pule blue or green narrowly edged with black, 
partly or entirely traversed by a median black line; there is no pale mid-dorsal stripe or line on 
abdominal segments 4-6, no prolongation of the transverse basal black band of 8 as stripes on the 
dorsum: their size is larger than any others recorded: abdomen 32, hind wing 26-27 mm. One of 
them has the blue antehumeral stripe half as wide as the black mid-dorsal, black humeral 14 times as 
wide as blue antehumeral, oval spot on 2 blue, the narrow transverse basal blue ring on 3-7 interrupted 
mid-dorsally and on 3 not connected with the mid-dorsal blue line, 10 black with two blue dorsal spots, 
mesostigmal lamina more like fig. 24, Tab. IV., than fig. 11. ‘The other female has blue antehumeral 
stripe one-third as wide as black mid-dorsal, black humeral equal in width to the blue antehumeral, 
the narrow transverse basal blue rings on 3-7 not interrupted, confluent on 3 with a narrow blue mid- 
dorsal stripe, 10 obscure, mesostigmal lamina as in fig. 11, Tab. IV. 
Of the seven pairs from San Pedro Sula, two females have pale Jabra, the other five black. The two with 
pale labra have a mid-dorsal blue stripe on 3 and 4 and a line on 5, dorsum of 10 chiefly or wholly 
blue, the mesostigmal lamina like fig. 11 or intermediate between figs. 11 and 15. The other five 
females with black labra have the mesostigmal lamina very like fig. 15 (difficilis), the mid-dorsal blue 
stripe on 3-5, or on 3 only with or without a pale line on 4; dorsum of 10 blue, or black with two blue 
spots. The dimensions of these San Pedro females fall within those given anted.
