the top of the head and the line dividing the epicranium may 

 be seen.* But previous to the present study, the eyes and 

 antennae had not been observed. Surprisingly few hind wings 

 have been described. Brongniart has figured some good ones 

 without description. f Goeppert in his Fossile Flora der per- 

 mischen Formation, Plate 28, figures under the specific name 

 Blattina neurojpteroides, what is evidently a small hind wing. 

 In Bulletin 121 of the U. S. Geological Survey, Scudder has 

 described several additional hind wings and reviewed those 

 that had come to his notice up to that time. The legs, with 

 the exception of the tarsus and basal elements, have previously 

 been described in a general way. . Deichmuller's Etoblattina 

 Haoellata, var. Stelzneri, preserves on the type specimen the 

 outlines of the coxae, trochanters, femora, and tibiae.;); The 

 Anthracoblattina sojjita Scudder {Blattina didyma Geinitz) 

 shows the femur and tibia of the second pair of legs and the 

 femur, tibia, and a part of the tarsus of the third pair.g Indi- 

 cations of legs have been noticed by various authors on a 

 number of specimens. 



The sword-shaped ovipositor first noticed by Brongniart [ is 

 one of the most striking differences between paleozoic and 

 recent cockroaches. The presence of the ovipositor can now 

 be verified from American material, and its structure more 

 fully described. Woodward had previously recognized the 

 presence of cerci on these fossils and distinguished the ten 

 abdominal terga, observing that the eighth and ninth, were not 

 reduced as in the living forms. The writer in a short paper 

 appearing in the April, 1903, issue of this Journal, gave some 

 additional structural characters of paleozoic cockroaches. Mr. 

 A. L. Melander in the February-March number of the Journal 

 of Geology, 1903, published, however, during the month of 

 April, figures an additional cockroach from Mazon Creek. 



Localities and Collections. — Almost all the American mate- 

 rial preserving the structure of the body has come either from 

 the Middle or Lower Coal Measures at Mazon Creek, Illinois, 

 or from the Upper Coal Measures at Lawrence, Kansas. In 

 the spring of 1901, the writer discovered the presence of fos- 

 sil insects among plants collected by Mr. Martin and himself, 

 from the Haverkarnpf farm near Lawrence. If Subsequent

■ff A single specimen from a nearby locality in the same formation, found 

 many years earlier by Mr. Joseph Savage, was sent to Lacoe and subsequently 

 described by Scudder as Etoblattina occidentalis (Mem. Boston Soc. Nat. 

 Hist., vol. iv, No. 9, p. 410, pi. 32, fig. 4, 1890).
