et sp. n. 



The genus Pinctodia is based upon two specimens each pre- 

 serving the body and parts of the wings. The head is rather 

 large. The thorax is of the arched, humped form common to 

 the family. The abdomen is proportionally short, being some- 

 what less than twice the length of the thorax. 



The segments of the abdomen are broader than long. 



Length of front wings probably not less than 15 mm . 



Length of hind wing not less than 14: mm .

Fig. 11. Pinctodia curia gen. et sp. n. Head, thorax, abdomen, base of 

 wings, and two legs preserved. The thorax and first five segments of the 

 abdomen are seen from the side. Between the fifth and sixth segments the 

 abdomen is broken and turned so that the remainder of the abdomen is 

 viewed from above. The abdomen is relatively short and thick as compared 

 with other genera of the family. The cross veins are indistinct. Those 

 shown are in part restored. The wings are mnch macerated, the impression 

 of the stronger veins only remaining. Enlarged 5 times. 



Scojnis gracilis gen. et sp. n. Text figure 12. 



This genus has a very long, slender abdomen ; slender, thin, 

 delicate wings ; and apparently rather long legs. The abdomen 

 of the type specimen is preserved complete ; the segments are 

 longer than broad. Two segments of the forceps are seen, 

 indicating a male. The caudal setse are apparently slender. 

 The wings, notwithstanding their thin texture, are strongly 

 corrugated. The cross veins are numerous but weak. The
