 Family PARALOGID/E Handlirsch. 

 PARALOGorsis, new genus. 

 Paralogopsis iongipes, new species. Fig. 58. 



An insect whose wings may have had a length of about 

 100""". The basal parts only being preserved, it is difficult to 

 give an exact description, but as this part is very similar to the 

 American genus Paralogies, described by Scudder, it becomes 

 possible to classify the fossil. 



The costa marginal, being separated from the snbcosta by a 

 single row of cells ; both veins are strongly convergent, so that 

 we can suppose that the snbcosta was not very long. Going 

 farther backward, we find a very thick vein which must be the 

 radius, apparently fused with the basal portion of the media. 

 On one and the same point of this vein rise 2 branches which 

 1 suppose to be the sector and the media. The subcosta-radial 

 space is filled by a single row of cells, just as is the space 

 between the media and the next following waved vein, which 

 I must call the first branch of the cubitus. Near the base we 

 find an oblique bridge reaching the last main vein or analis. 

 This bridge evidently is the second main branch of the cubitus, 

 temporarily uniting with the anal vein ; farther outward the 

 cubitus again becomes independent. The interstices between 

 the two cubital branches and the anal vein show but one row 

 of cells. The anal vein sends off numerous more or less broken 

 branches and intercalary veins toward the posterior margin, 

 all being united by cross veins. 



The front wings are narrower than the hind wings (16""" 

 and 20 mm ), slightly reduced toward the base and not angular. 



One of the legs, probably of the posterior pair, is preserved ; 

 its femur must be described like the tibia as very slender and 

 reaches 24 ram . 



I cannot say whether my interpretation of the sector is right 

 or not. Should the opinion of Mr. Sellards, who supposes that 

 the crossing of sector and media was complete in the Palaeo- 

 zoic Protodonata, be ratified, the vein which I consider to be 

 the sector should be added to the media. In any case we will 

 await new discoveries before deciding this question. In the 

 European Protodonata I have not seen a sign of such a cross- 

 ing and even Paralogus Scudder does not confirm Sellards' 

 opinion.

Order MEGASECOPTEEiA Handlirsch. 



Among the fossils now examined there is a very shadowy 

 one showing nothing but the four wing cases of a nymph.
