Oryctoblattinidce. 



The family Oryctoblattinidse has been erected recently by 

 Handlirsch and is placed by liim among the Protoblattoidea.* 

 The genera referred to this family by its author are as follows: 

 From the Carboniferous ; Oryctoblattina Scudder, Blattinopsis 

 Giebel, Anadyomene K. v. Fritsch, Glaphyrophlebia Hand- 

 lirsch, Microblattina Scudder, Prisca K. v. Fritsch, and Phi- 

 pidioptera Brongniart ; from the Permian, Oryctomylabris 

 Handlirsch, and Pseudoftdgora Handlirsch. Two additional 

 genera obtained from the American Permian are added in the 

 present paper. 



The family contains several forms of particular interest. 

 The genus Phipidioptera was originally referred by its author, 

 Brongniart, directly to the Homoptera, and to the recent 

 family, Fulgoridge.t The forms known in literature as Ful- 

 gorina Goldenbergii Brongn. and F. ovalis Brogn., and regarded 

 by some as Homoptera, are included in this revised classification 

 in the genus Blattinopsis Giebel. The Permian form known 

 as Fulgora Fbersi Dohrn (Fidgorina Fbersi Gold. ) stands as 

 the type of the new genus Pseudofulgora Handlirsch. Some 

 of the other genera, including the type genus, Oryctoblattina, 

 bad been previously regarded as cockroaches. It is thus seen 

 that the family is made up of forms originally referred to 

 very diverse groups. The geological range of the Oryctoblat- 

 tinidae as now known is through the Upper Carboniferous, and 

 into the Permian. 



The wing venation in this family is characteristic. The 

 numerous veins uniting the subcosta with the costa have the 

 appearance of cross veins rather than of oblique branches, 

 differing in this respect from the blattid wing. Subcosta and 

 radius are distantly separated and are united by oblique cross 

 veins. The radical sector arises early and is repeatedly sub- 

 divided. The media is two to several times branched. The 

 cubitus has usually numerous inferior branches. The anal 

 area is marked off by a thin depressed line, and is traversed 

 by a few strong veins. 



That part of the wing lying between the sector and the 

 cubitus affords the specially characteristic features of the vena- 

 tion. IViost genera have a plainly marked line extending 

 across this area from the cubitus to, or beyond, the sector, thus 

 marking off the basal from the apical half of the wing. This 

 cross line is plainly marked in Blattinopsis, Anadyomene, 

 Prisea, Pseudofulgora, the two Permian genera described 

 below and in two undescribed genera obtained by the writer
