THE PUPA OF MERMIRIA TEXANA BRUNER. 



BY T. D. A. COECKRELL, EAST LAS VEGAS, N. MEX. 



Orthopterists have not usually paid 

 much attention to the pupae of grass- 

 hoppers ; partly, no doubt, because they 

 rarely offer any remarkable characters, 

 and partly because they often shrivel 

 and lose their natural colors, when 

 pinned in the cabinet. The pupa of 

 Menniria texana, now described, is a 

 very striking and beautiful creature 

 when alive, and it seems well worth 

 while to present an account of it. 



9 . Length 34-36 mm., antennae \o\ 

 mm., dorsal surface of head 5J mm., 

 pronotum 5^ mm., teginina 8 mm., end 

 of tegmina to tip of abdomen 16-18 

 mm., femur i6 mm., tibia 15 mm., 

 breadth of thorax 4 mm. 21 spines on 

 outer margin of hind tibia. Brown of 

 various shades, with pure white longitu- 

 dinal stripes ; top of head with a broad 

 median longitudinal pale sepia band, 

 narrowly edged with darker; on each 

 side of this a broad pale apricot or red- 

 dish-ocherous band, clouded with pale 

 gray, and externally bordered with 

 white, the white border running through 

 the upper edge of the eye ; next to this 

 a broad dark sepia band, also bordered 



below with white; then a dilute gray 

 band, marbled with lighter veins and at 

 its lower part spotted with darker ; this 

 lower spotted part bordered below with 

 white ; running from below the eye, 

 bordering on the lateral carinae of the 

 face, is a pale reddish-ochreous band. 

 Eye gray, its upper part spotted, its 

 lower part striped with grayish-white. 

 Face gray mottled with blackish, the 

 median carinae pale. Antennae a warm 

 brown, distinctly triquetrous towards 

 base, not nearly so broad as the shorter 

 diameter of the eye. The prothorax 

 continues the longitudinal markings of 

 the head, but the median zone, is mot- 

 tled with dark gray, and its ground color 

 is inclined to purple, with the median 

 carina, which is very distinct; is indi- 

 cated by a pale line. The subdorsal 

 dark band passes backwards along the 

 thorax and abdomen, crossing the teg- 

 mina, which thus have their lower half 

 dark and the upper a light warm reddish- 

 ochreous. On the sides of the thorax 

 the dark band is broadly bordered below 

 by white ; but on the abdomen it is nar- 

 row, and is bordered aboi'e by white.
