320 Handlirsch — New Paleozoic Insects from the 



Family APITHANID^E, new family. 



A very singular slender insect, differing from all other groups 

 of the Protorthoptera, induces me to establish a new family. 



The pear-shaped prothorax is of a moderate length; the meso- 

 thorax somewhat enlarged, bearing the comparatively broad 

 anterior wings, which show a singularly specialized venation 

 and could be laid backward over the abdomen. The metatho- 

 rax conspicuously shorter. Abdomen slender, its first segment 

 being the shortest of all, nearly twice as broad as long, the 

 second about quadrate, the following to the seventh much 

 longer than broad. The end of the abdomen and the posterior 

 wing not being preserved, I am not able to say anything 

 regarding the appendages and the anal lobe. The (? anterior) 

 legs were short and delicate. 



The venation of the anterior wing is a characteristic one: 

 the costa marginal; subcosta shortened, united with the costa; 

 radius with a short sector, rising outward from the middle of 

 the wing and forming a simple fork. Media independent, 

 cleft near the middle of the wing into 2 branches. Cubitus 

 divided near the base into 2 main branches, the anterior strongly 

 waved and making a short terminal fork, the posterior 

 trichotomous. Anal area slender, reaching half the length of 

 the wing and containing few veins. Cross veins simple and 

 oblique in the costal and subcostal area, elsewhere evidently 

 very rare. 



Apithanxjs, new genus. 



Apithanus jocular is, new species. Figs. 26, 27. 



Prothorax 5 mm long, one and a half times longer than 

 broad. Mesothorax nearly quadrate. Metathorax one and a 

 half times broader than long. First segment twice as broad 

 as long, shorter than the metathorax; second segment quadrate; 

 the third to the seventh each longer than broad. The middle 

 line of the abdomen showing tubercles on the base and apex 

 of each segment. The femora of probably the fore legs short 

 and delicate, doubtless not exceeding the length of the protho- 

 rax. Anterior wings 30 mm , three and a fourth times longer 

 than broad, dilated in the apical half. Apical margin obliquely 

 rounded. Costa marginal, slightly waved. Subcosta extend- 

 ing nearly two-thirds the length of the wing, uniting with 

 the costa and giving off about 7 oblique veinlets. Padins 

 very close to the subcosta in the basal third, farther outward 

 more remote, the interstice being traversed by 5 oblique cross 

 veins. Sector not rising before the middle of the radius, from 

 which it is separated by a broad interstice, and forming only 

 one broad fork. Media quite free, cleft somewhat before the
