outer margin of wings, and anotlier at end of lower fork near end of anal vein. 

 Wings rather narrow ; hut few costal cross-veins forked ; venation on usual plan. 

 Length 27 mm. 



Laredo, Texas (McClendon). Similar in appearance to B. longi- 

 catiiiiis but markings of head, pronotum and legs entirely different. 



Myrmeleon mexicanum, sp. nov. 



Head black, shining below antenna and the scars on vertex ; lower part of face 

 pale yellowish as well as along eyes ; pronotum brown, with a pale yellowish spot at 

 each anterior corner, and sometimes two near the middle ; rest of thorax gray-brown, 

 abdomen same color, last segments partly pale ; legs pale yellowish, marked with 

 black, femora with a long black spot above near tip ; tibia with a black spot before 

 middle, and a band at tip ; the tarsi tipped with brown. The pale parts of the legs 

 are not dotted. The black spot on middle femora is larger than the others. Wings 

 hyaline, the longitudinal veins (except anal) interruptedly yellow and black, other 

 veins black ; pterostigma small, white. Length 35 mm., expanse 74 mm. 



Several specimens from Guadalajara, Mexico (McClendon). 



It differs from M. abdominalis in not having black dots on the 

 pale parts of the legs, and no pale spots on abdomen, except at tip. 

 It differs from M. occidcntalis in having the hind femora pale, with 

 only a black patch above and more white on face. 



TRICHOPTERA. 

 Glyphot^lius bellus, sp. nov. 



r'ace and vertex brownish, with short grayish hair, posterior margin with longer 

 erect hair; antennae yellowish, basal articles rather long, ocelli small, vertex flat; 

 prothorax short, with long yellowish hair; meso- and metathorax yellowish, with a 

 black stripe each side ; abdomen brown ; legs yellow -brown, spines small and black. 

 Anterior wings yellow in anterior half, brown on posterior half, a long silvery streak 

 in thyridial area nearly to base separates the two parts, this crosses the anastomosis 

 and extends into fifth apical cell for one third its length ; another silvery streak in 

 fourth apical cell nearly to base ; the outlines of these streaks are very clear near 

 anastomosis ; another hyaline streak in apical part of first subapical cell ; a faint trace 

 of a silvery streak along posterior edge of radius. Pterostigma rather darker than its 

 environment ; venation yellowish. Wing long ; posterior apical margin plainly ex- 

 cised ; pedicel of discal cell as long as cell ; second and fourth apical cells broad at 

 base ; radius at pterostigma curved. Hind wings hyaline ; the third, fourth and fifth 

 apicals extend nearer base than others ; a black dot in base of third. Length to tip 

 of wings 26 mm. 



One specimen from Nanaimo, British Columbia, September 3 (Tay- 

 lor). This species differs much in appearance from G. hostilis ; the 

 incision of apex of wings is an even one, and the wings are much nar- 

 rower; the basal joints of the antennce are not as long, and the pro- 

 thorax is shorter.
