IO2 MELANDER. 



in no manner deciduous. Hence the wingless male described 

 below cannot be considered as a dealated form. Herewith is 

 given a more detailed characterization of the male. Aside from 

 the description of the wings it will ^apply'for the wingless form 

 mentioned later on. 



EMBIA TEXANA Melander. 



Male. Length 6 mm., length 'of antenna 3 mm., length of wing 4.5 mm. 



Clear-cut, slender species. Body black, with violaceous or bronzed 

 reflection ; head, prothorax and front femora castaneous brown, middle 

 and hind legs sometimes also brown, but darker ; black-villose, the hairs 

 variable in length and number. Antennae black, the individual joints pale 

 on their outer fifth, seventeen joints present, and these equalling a little 

 more than one half the body-length, i. e., reaching to the end of the meta- 

 thorax, basal joint stout, cylindrical, a little longer than wide, second joint 

 of less width, quadrate in profile, the remaining joints elongate-pyriform 

 becoming elliptical terminally, the individual joints about as long as the 

 basal two ; all the joints are provided with stiff radiating black hairs. 

 Palpi of same structure as in the larva, the maxillary palpi black, the labial 

 reddish at the base. The lighter spaces of the head and thorax of the 

 larva are much altered, becoming faint and indefinite in the adult. Pro- 

 pleurae with two small sharp black tubercles in front of the coxa?. "Thorax 

 and abdomen as in the larva, but the chitinization and pigmentation much 

 more advanced ; penultimate segment (ninth including the segment medi- 

 aire) narrow, somewhat bullate dorsally towards the right ; ultimate seg- 

 ment asymmetrically bisected dorsally, each portion produced more or less 

 conically and pointed, in the middle of this armature, between the two 

 titillatores a fleshy process may be exserted. Last ventral segment tri- 

 angular, simple, but the left side is somewhat excised. The dorsal struc- 

 ture is not visible from below. The left cercus large, single-jointed, 

 clavate, obliquely truncated apically, the right appendage two-jointed, 

 with its outer joint shorter than the inner, both appendages hairy. Wings 

 brown, marked with five secondary veins of wine-red pigment, the second 

 and third connected by two to four cross bands of pigment, the third and 

 fourth sometimes also connected. The central space of the cells is clear 

 hyaline. 



In this species the venation of the wings is much reduced, only 

 the base of the subcosta, the radius, the cubitus, and the indefinite 

 base of the anal vein exist as thickened cuticle ; the original ve- 

 nation is represented by bands of wine-red pigment arranged like 

 lines of granulations and by series of short hairs. These lines 

 extend just posteriorly to the cuticular thickenings and represent 

 the full venation of the nymph, except that the costa is wanting
