Valve hroadly oval, tap<*ring hy nearly straiglit lim^s to the sul>acnteapi<."es; raphe 

 e\tensi\ely curved near tlu^ apices toward opj)o«it(^ sides, and sharply bent at the 

 <-enlt'r toward the same side: olln^rwise straight; markings (»f large massive Ix^ads^ so 

 arrangcil in roAvs as to give curv<'d lines, ohlitpie to the raplK% in two directions; 

 hyaline space much broach Ton one sidc^ of the I'aphe than <tn the other (AUoineis tv ])(;); 

 a distinct bortler of strong, closely set lines perpendicular to the margin, l)roadest at 

 tlie crni or of the valve and narrowing ]m)portionately toward its api(^es; a large hyaliue 

 siaurosat tliec(mter, about one^-half the width of the valve. 



T.engih of valve, 0.128 uiui.: width of valve, 0.0(i2 mm, C'nrved oblifiuo striae (at 

 center), 40 to 45 in 0.1 mm.; ra<liating striae (at center), 75 to 80 in 0.1 nun.
