Psyche 



[April 



This specimen is apparently a male, as indicated by the shape 

 of the abdomen and the absence of hypopygium or ovipositor 

 sheaths. The second dorsal abdominal segment in this species is 

 relatively larger than in A. -progenitrix, and the insect has a length 

 1.5 mm. greater than in any other known Aulacidea. 



Aulacidea succinea sp. nov. 



Female. Head: about as broad as the thorax; palpi 4 (?)- 

 jointed; antennae 14-jointed, the first joint obconical, elongate, the 

 second globose, the third joint the longest, more slender than and

as long as 1 plus 2, remaining joints diminishingly shorter to the 

 13th, 14th about as long as the 12th, and with a short pubescence 

 absent only on the basal half of the antennae; the antennae originate 

 about on the mid-line of the eyes. Thorax: distinct parapsidal 

 grooves extending to the pronotum, converging slightly toward the 

 scutellum; the scutellum longer than wide, with two large, broad, 

 moderately deep foveae. Abdomen: with plates 2-6 visible, the 

 2nd about one-half the total abdominal length, plates 3-6 sub- 

 equal in length; hypopygium regular, abruptly ending, the tip 

 pubescent. Legs: the tibiae very slender; 1st tarsal joint almost 

 half the total tarsal length, 4th joint the shortest; claws simple.
