178 Mr. R. M‘Lachlan’s Monograph of the 
PLATE III. 
Fig. 1]. Neuration of Phrygunea grandis, g; 1a, apical portion of wings 
of 9; 1b, maxillary palpus of ¢; 1c, labial palpus of ¢; 1d, 
maxillary palpus of 9. 
2. Neuration of Newronia ruficrus ; 2a, maxillary palpus of ¢; 26, 
labial palpus of ¢; 2c, maxillary palpus of 9. 
3. Neuration of Agrypnia Pagetana. 
4. 5 Cotpotaulius incisus. 
5. 39 Limnephilus flavicornis. 
Inpex wincs. A, anterior wing: a,subcosta; b, radius; c, ramus 
discoidalis ; d!, superior branch of ramus thyrifer; d?, inferior 
branch of ramus thyrifer; e, cubitus; f, pterostigma ; g, dis- 
coidal cell, which is either ‘‘ closed” by a transverse vein, as in 
this species, or without any transverse vein, in which case it is said 
tobe ‘‘ open”; h, cellula thyridii ; i, thyridium, a pale spot found 
in many species ; j, arculus, frequently indicated by a pale spot ; 
k 1—k 9, apical cells ; 1, apical sectors; the anastomosis is the 
row of transverse nervures placed about the middle of the wing ; 
it is said to be ‘‘complete” when a transverse vein is placed 
between each of the longitudinal ones (not counting the costa 
and subcosta ), and ‘* incomplete’’ when some of these transverse 
veins are absent. 
B, posterior wing: a, ramus discoidalis; 6, ramus subdis- 
coidalis ; c, cubitus; d, costule ; e, pterostigma ; f, discoidal 
cell; g 1—g 7, apical cells ; h, apical sectors. 
6. Neuration of apical portion of wings of Limnephilus vittatus. 
PLATE IV. 
Fig. 1. Neuration of Grammotaulius nitidus; 1 a, maxillary palpus of 
Limnephilus pellucidus, @; 1 6, maxillary palpus of 9; lc, 
labial palpus. 
2. Neuration of apical portion of wings of a Limnephilus centralis in 
which the arrangement is very abnormal and unequal; 2 a, right 
wings ; 2.a,, left wings. (I have not seen another instance of 
aberrant neuration that bears the slightest analogy to this.) 
3. Neuration of Anabolia nervosa. 
4. FS Stenophylax stellatus ; 4 a, maxillary palpus of ¢@; 
4b, maxillary palpus of 9; 4 c¢, labial palpus. 
5. bs Halesus digitatus. 
6. oe Ecclisopteryx guttulata. 
We af Phacopteryx brevipennis. 
8. Be Chetopteryx tuberculosa ; 8 a,an apical cell, magnified; 
8b, maxillary palpusof ¢; 8e, maxillary palpus of 
¢; 6d, labial palpus. 
9. ay Apatania vestita ; 9a, maxillary palpusof ¢; 9 4, labial 
palpus. 
10, s Sericostoma Spencii.
