10 Mr. T. D. A. Cockerell on Fossil Arthropods 
its extreme end; first r.n. strongly arched, second r.n. 
gently bowed outward. 
H. 1036. This is certainly very like the modern Poly- 
sphincta. There is some resemblance to Promethus and 
Metanomalon, but it is distinct from both. 
Lampronota disrupta, sp.n. (Fig. 9.) 
Anterior wing 5 mm. long; wings clear, with fuscous 
stigma and nervures ; head and thorax black, abdomen 
perhaps paler ; abdomen fusiform, narrowed basally, with a 
probably long straight ovipositor, of which not more than 
1 mm. is preserved ; hind femora long and slender, length 
about 2°2 mm.; antenne long and slender, apparently 
Fig. 9. 
Lampronota disrupta, sp. n. 
entirely black. Marginal cell lanceolate; b.n. meeting the 
oblique t.-m. 
B.M., I. 9711 (B.). The abdomen is separated from the 
thorax, but appears to belong to the same specimen; its 
base is near the anal angle of fore wing. This is not 
Bassus, but clearly Lampronota. 
Polyclistus (?) anglicus, sp.n. (Fig. 10.) 
Head, thorax, and antenne black ; anterior wing 3 mm. 
long, dusky hyaline ; stigma fuscous, nervures pale brown ; 
m. deep, angled at t.-m., r. 2 very gently curved; b.n. 
strongly curved or bent ; t.-m. extremely oblique.
