NORTH AMERICAN NEUROPTERA. 205 



Mesilla, New Mexico, June (Morse). 



A very pretty species, reatlily known by the pule radial sector. 



Braehyiieniui'iis coqnilletti Carrie.— Can. Entoni., 1898, p. 93. 



Two specimens from Coronado, California (July), agree with the 

 description. It is readily known by the pale vein between radius 

 iind median. Distinguished from B. tenuis by broader wings at 

 tips, absence of large spots on median, absence of spots on hind 

 wings, different thoracic markings, shorter genital apparatus, etc. 



The species of Brachynemurtis known to me may be separated by 



the following table: 



1. Labial palpi loiiojer than head loilgipalpi. 



Labial palpi much shorter 2. 



2. Wings plainly yellowish, nearly evenly marked all over with small blackish 



points, hind femora scarcely, if at all, pointed with fuscous. 



ab<loiniiiali!>«. 



Wings not plainly yellowish, dark spots mostly along radial and median 



veins 3. 



3. Abdomen plainly marked by large transverse pale spots Naf'keni. 



Abdomen not so marked 4. 



4. Two series of costal areolets almost to base of fore wings, none of fuscous 



points on wings very large, size medium loiigi<*aii<liis. 



Not two series of costals areolets as far to base of wings . .5. 



5. No dark points at ends of cross-veins on hind part of fore wings, excei)t at 



• end of anal vein 6. 



Many small points at ends of cross-veins in hind part of fore wings 9. 



6. Median vein without small cloud-like projections, labrum black. 



iiigrilabris. 

 Median vein with dark projections 7. 



7. Larger, darker, no fu.s<!ous markings on the forks of veinlets beyond end of 



cubital vein ferox. 



Medium size, paler, some fuscous marks on forks of veinlets beyond end of 

 cubitus 8. 



8. Cubitus faintly marked, there is a series of clouded gradate veinlets starting 



from end of cubitus peregriiius. 



More dark on cubitus, the cross-veins from end of cubitus do not form a gra- 

 date series, paler than i)receding 4-piiiiCtatiis. 



9. Vein between radius and median (just behind radial sector) for a considera- 



ble part of its length pale 10. 



The above vein interrupted with black or brown throughout 11. 



10. Radial sector on basal part wholly yellow, dark dots in hind basal part of fore 



wing are on the margin tenuis. 



Eadial sector dark, dots in bind basal part of fore wing are mostly near anal 

 vein voqtiillelti. 



11. A vertical line between bases of antennae, pterostignia of hind wings without 



a dark mark interiorly, many costals of front wings forked before the 

 ptcrostigma piiinilJN.
