A ro-examination of my North American Microjitcnj.r panJclla and 

 3/. autinindla show.s them to belong to a new genu.s, for which 1 

 propo.se the name Epimartijria. It resembles Eiiucronia in general 

 appearance, but has the jaw structure (without tongue), of a true 

 Miciojiteryx, and very peculiar antennae. Ejiiniarti/ria, therefore, 

 is the American representative of Micrnpterijx, lib. [Kriucejilutla, Crt.), 

 with developed mandibles.

{'eirifMapTvpia = testimony). 

 Type : Kjdmartyria jiardella, Wlsm. (United States). 



Antennae (|) moniliform, each bead with a fringe of long hairs 

 from the circle of its widest diameter, projecting forward as far as the 

 middle of the bead above it. Mandibles developed. Jlau.steUiiin absent. 

 Labial Palpi (not observed with certainty, ? absent). Ma.cillari/ 

 I'alpi strongly developed, r)-jointed, scaled, hairy on the basal joints, 

 curved inward. Ma-rilhe distinct. Ocelli present. Head and Face 

 very rough. Fure-tvin<is with the costa somewhat excavate at the base, 

 thence slightly arched, apex rounded ; .somewhat widened across the 

 middle. Xeiiratioi lb furcate at base, connected by a bar with le, 

 which has a small fork at the extreme base ; vein 2 out of 8 imme- 

 diately beyond angle of lower cell, 2 + 8 (= cubital) continued to 

 near the i)a.se, but becoming furcate before the bar from 1/* to Ic ; the 

 lower liud) of the fork is almost obsolete, and goes to If, the upper 

 is distinct, and goes to the median (4 + 5 + ^j ! •! furcate, one limb 

 going to cubital before origin of 2, the other limb to median at about 

 f, at which point 5 is bent down to unite with it ; ;"> and G .separate, 

 and almost parallel, furcate at base, connecting median with radial ; 

 7 and H stalked (7 to slightly above apex), and continued through cell 

 to about midway between 11 and 10 ; the transverse veins joining 10 

 to 9, I) to 7 + H, and 7 + 8 to 6 are weak, and that between 9 and
