THE CANADIAN ENTOMOLOGIST. 59 



There is not much variation. Texas specimens have on the front part 

 of the prothorax two brownish spots, and younger specimens are more 

 bright in colors ; a number of specimens have the spurs longer, equal to 

 the three basal joints, though others of the same locality have spurs two 

 joints long, M. juvencus Hag. is Myrm. abdominalis Say. 



5. Brachynemurus peregrinus. 



Myrmeleon peregrinus Hag., Syn. N. Am. Neur., 234, 20. 



Face yellow, with a short black band above, surrounding the antennae 

 below ; sending a faint black median line on the upper part of the face, not 

 reaching the clypeus ■ mouth yellow ; palpi yellow, the maxillary with the 

 last joint cylindrical fuscous ; labials a little longer, last joint shining 

 black, extreme base and tip yellowish, seen from above strongly fusiform 

 with a kind of ocellus-like transparent median spot ; seen from beside 

 the joint is less bulky, the third apical part strongly narrowed, conical. 

 Antennas longer than head and thorax, strong, clavate, black, scabrous, 

 dull, the two basal joints below shining brown ; the base and apex of the 

 antennae sometimes pale brown, and very faintly annulated ; vertex ele- 

 vated, rounded, yellow ; black in front with three not well defined yellow 

 dots and two black transversal bands, the last one interrupted in the mid- 

 dle, and arcuated ; prothorax scarcely longer than broad, yellow on the 

 dorsum, with four longitudinal black lines, and beneath on each side with 

 a black stripe ; the pattern of the dorsum and its many variations is better 

 to be understood in describing it as black, divided by a narrow yellow 

 line and each part divided again by a yellow line not reaching the front ; 

 broken in the middle and forming two elongate spots, of which the inferior 

 ones may disappear ; mesothorax black with yellow dots near the pro- 

 thorax ; after this yellow with three black forks ; metathorax yellow with 

 a black cross ; sides of thorax black with some yellow bent stripes. 

 Abdomen faintly villous ; above yellow with three longitudinal black 

 bands, the median much finer on the male, which has the three last seg- 

 ments black ; venter fuscous ; abdomen of male much longer than wings ; 

 appendages light brown with very long black hairs and bristles, very 

 short, blunt pyramidal, divergent ; between them and below a small plate 

 of the shape of a leaf, which can be folded in the aperture between the 

 appendages ; abdomen of female as long as the wings, dilated and com- 

 pressed to the apex ; genitals light brown, the superiors split, below with 

 a transversal row of very strong black spines ; below two short cylindri-
