Sigalphus (?) cervicalis, sp.n. (Fig. 15.) 
Length slightly over 2 mm.; anterior wing nearly 2 mm. 
long, clear, nervures pale ferruginous. Head and prothorax 
dark fuscous, rest of body as preserved pale ferruginous. 
Head transverse ; neck elongated; thorax with posterior 
lateral spines ; abdomen broad ; ; stigma robust; m. long, 
its angle at the oblique t.-c. little greater than a right angle, 
its margin beyond this straight; disc. 1 acutely pointed 
above, reaching subcosta. 
B.M., 1.9199 (B.). 
Probably a Siyalphus, but differs in shape of disc. 1 and 
straight b.u. ‘The wing shows some resemblance to 
Centistes, but has r. 2 curved. 
Xenarcha (?) distracta, sp.n. (Tig. 16.) 
Length 2:1 mm.; anterior wing about 2 mm., hyaline, 
faintly reddish ; stigma dark rufo- fuscous, nervures paler. 
Stigma large ; m. large, r. curved, not distinctly angled 
Fie. 16. 
Xenarcha (?) distracta, sp. n. 
» Sp 
at t.-c. ; second t.-c. obsolete, but represented by stumps of 
veins ; disc. 1 just meeting corner of second s.m., forming 
a cross; posterior nervure leaving lower apical corner of 
disc. 1 ; abdomen short and robust. 
B.M., I. 9099 (B.). 
From the venation this would appear to be a Hormiine, 
rather close to Chremylus, but that genus has the second 
s.m. complete and the stigma more lanceolate. //ormius 
agrees with the fossil in the stigma, but has second s.m.
