SPHINGONOTUS TRINESIOTIS ALBEMARLENSIS 



var. nov. 



From Tagus Cove, Albemarle Island. 



Description of the Type. Male. — General tone of coloration dull 

 reddish-brown, everywhere more or less mottled or spotted with 

 black. Top of head, frontal lunule, and frontal costa as far down as 

 bases of antenna, dusky, the frontal lunule mottled with orange; on 

 each side of vertex a darker colored groove curving outward poste- 

 riorly ; a narrow orange post-ocular stripe running backward and in- 

 ward a little above the middle of the eye ; genje below this stripe pale 

 slate-colored ; clypeus and lower part of front spotted everywhere with 

 black on a reddish-brown ground ; labrum slaty, punctate with black. 

 Antennas dusky, each segment annulate with orange, this color espe- 

 cially prominent basally, the black predominant distally. Pronotum 

 dusky on dorsal surface, above on each side an indistinct, orange stripe 

 continuous in front with the narrower post-ocular stripe, posteriorly 

 the two diverging to the outer posterior angles of the metazona; on 

 the prozona below the orange stripe a wide black stripe on the lateral 

 angle, next below this a narrower slate-colored stripe followed by a 

 wider black stripe again ; the rest of the prozona and the sides of the 

 metazona reddish-brown with black mottlings and punctations. Sides 

 of mesothorax and metathorax reddish-brown with small closely dis- 

 tributed black spots, making the general color dusky. Fore and middle 

 legs reddish-brown, black spotted. Hind femora having a decidedly 

 reddish tinge with a slaty tone along the outer side, each crossed above 

 by two black bands reaching from the inner lower carina to the outer 

 lower carina ; on the outer side neither of these stripes is definitely out- 

 lined and each is obliquely inclined from above downward and for- 

 ward ; posterior enlargement of femur mottled with black giving it a 

 dark appearance so that the femur appears marked with three transverse 

 dusky areas. Hind tibia and tarsus yellowish, mottled with black, 

 spines all black-tipped. Abdomen reddish-brown and slate mottled 

 with black. Tegminal membranes pale transparent brown, color deep- 

 est basally, veins and reticulations dark brown ; at about a third of the 

 length of each tegmen from its base to the tip a large dusky blotch made 

 up of numerous small fused spots ; the blotches of the two tegmina 

 meet above forming continuous cross-bands ; half way between each 

 of these spots and the tip of the tegmen a second small blotch confined 

 to the side of the wing and of a brown color rather than black ; 

 beyond this numerous much smaller brown quadrate spots, and a few 

 very small ones between the two large blotches. Posterior wings with
