largely pale, -with a narrow dark stripe reaching as far as the trans- 

 verse furrow. The wings are similar to that species, with clotted 

 veins, and longer dark spaces on subcosta, radius and cubitus. 

 In fore A\nngs are about seven cross-veins before radial sector, in the 

 hind wings about four such cross-veins, in both pairs eight branches 

 to the radial sector. Expanse 53 to 55 mm. 



From Claremont, Calif., and Nogales and Phoenix, Ariz. 



Myrmeleon heriocles n. sp. 



Face shining black, in front with two submecUan projections, 

 mouth and cheeks pale, tips of palpi dark; vertex black, wdth trans- 

 verse row of more or less shining rufous spots; antennae black, basal 

 joints pale; pronotum dull black, but lateral half of anterior part 

 pale, and the margin of posterior part also pale; thorax dull black, 

 with pale yellow stripe through the bases of the wings, continuous 

 with the pale margin of pronotum; abdomen dull black; legs pale, 

 broad dark bands on middle of the femora, narrow bands near base 

 and at tip of tibiae I and II, most of tarsi black, hind tibia with 

 black stripe within; wings hyahne, veins dotted with dark, the 

 subcosta, radius, and cubitus with longer dark spaces,, stigma dark. 

 In fore wings about nine cross-veins before radial sector, in hind 

 wings six or eight such cross-veins, ten branches to radial sector in 

 each wing, in fore wings three cross-veins between anal and cubital 

 fork, in both pairs the tips are acute. Expanse 70 to 73 mm. 



From Southern Pines, N. C, in May; also occurs in Florida. 

 I had considered this as probably the M. tectus of Walker, but a view 

 of the type shows that it is a different species. 



Macronemurus darwini n. sp. 



Face pale yellowish, with a median vertical dark mark, a dark 

 spot below each antenna, vertex mostly dark, but usually pale each 

 side near eye; antennae pale, darker at tip; palpi pale; pronotum 

 pale, with a pair of submedian brown marks, sometimes faint; 

 thorax yellowish brown, indistinctly marked, but usually with a 

 pale median line; abdomen dark, often pale at base and some seg- 

 ments pale at base above, legs pale, unmarked, spines black, spurs 

 equal two tarsal joints on front legs. Wings with the longitudinal 

 veins spotted with dark, and most of the cross-veins dark at one or 

 both ends ; in both wings is a long dark brown streak from near end 

 of median and cubitus out toward tip, and usually a series of spots 

 beyond the stigma to near the tip. In fore wings six cross-veins 

 before the radial sector, eight or nine branches to the radial sector
