24 AMERICAN NEUROPTERA. 



HEMEROBIIDJE. 



Berotha texana n. sp. — Length 9 mm. Face pale yellowish, vertex dotted 

 with l)lack, esjiecially near the eyes, palpi reddish, antennae pale yellow; pro- 

 thorax short, highest in the middle line, crossed by two furrows, dull yellowish, 

 with fuscous dots; meso- and metathorax still darker. Abdomen blackish. Legs 

 pale, with fuscous dots ; body and legs clothed with short white hairs, and long 

 black and some white bristles. Wings narrow, hyaline, excised below tip which 

 is acute, hind wings much less so than in M. jiavicornis, veins fuscous, dotted with 

 white, along the costal margin are three or four more prominent dark spots before 

 the pterostigma, the latter is fusoous; fringe on fore wings interruptedly white 

 and gray, on hind wings gray, transverse veins fuscous, five branches to the 

 radial sector. 



Two specimens, Central Texas. Differs from B. Jiavicornis in 

 smaller size, darker colors, costal spots, etc. 



HE9IEROBIITS. 



A large number of species have been described, most of them, 

 however, closely related. They have been arranged in three groups, 

 according to the number of sectors to the radius. 

 Group I. — Two sectors. 



Two species, both described by Fitch, belong here, H. cmiiculu^ 

 and H. oceideiitalis, the former I have from Long Island, N. Y., 

 the latter from Colorado. 



Group II. — Three sectors. 



Here belong the great majority of species, only a few of which I 

 have been able to identify. They can be arranged in two sections. 



Section A. — The cubitus bent toward the post-cubitus, thus making 

 one of the connecting veinlets shorter than the other ; usually no 

 veinlet connecting cubitus and first sector. 



Heinerobius ca!!»taiiie Fitch. 



This is a very common species, and doubtless described by Walker. 

 The genitalia come nearest to the European H. micaiis, as figured 

 by McLachlan, but the superior branch is rather longer and sharp 

 pointed. It is not the H. hamuli. 



Heiiierobius stigiiiatertis Fitch. 



Less common than the preceding. Very close to the European 

 H. litnbatasWuesni., and probably identical. According to McLach- 

 lan two of Walker's species from the United States, H. obliteratus 

 and H. crispu.^ are H. limbatus. 



Henierobius pacilicus n. sp. — Alar expanse 19 mm. Head pale, a 

 brown stripe below each eye, and a line at base of antennae, the latter pale, tho- 

 rax pale, hardly brown each side, legs and abdomen pale, veins of wings pale
