type). 
Stereopterum maculosum, n. sp. 
Text- figure 13 
Fore wing: length, 8.5 mm., width, 3.2 mm. (holotype); more 
slender than that of rotundum ; Rs usually with some coalescence 
between Rs and MAi ; CuA or CuAi anastomosed with stem of M; 
cross veins in area between CuA and CuP forming a very coarse 
network ; wing distinctly coriaceous, with numerous irregular macula- 
tions, preserved as reddish-brown spots. 
Holotype: No. 15653, Peabody Museum of Natural History, 
Yale University; collected in the Elmo limestone by C. O. Dunbar. 
This consists of a nearly complete wing, lacking the anal area and 
portions of the wing base and anterior margin. 
Paratypes: No. 5257, Museum of Comparative Zoology; collected 
in the lower layer of the Elmo limestone by F. M. Carpenter; this 
consists of a nearly complete fore wing, lacking only the basal part; 
a plant fragment rests near mid-wing, obscuring the veins in a small 
area. No. 4958, Museum of Comparative Zoology, collected in Elmo 
limestone, lower layer, by F. M. Carpenter. This consists of a nearly 
complete fore wing lacking the apical quarter and parts of the hind 
margin and anal areas. This is the only specimen of maculosum which 
shows the basal part of the wings; the peculiar lobe at the base of 
the costal area is not present, although there are several prominent 
spines along the costal margin basally, much as in rotundum. 
Apart from its shape, maculations, and more pronounced coriaceous 
texture, this wing differs from that of rotundum by the more widely 
spaced cross veins and the coarser network between CuA and CuP.
