yellow. Venter yellow fasciate at the incisures. Legs dark pitchy black, the hind 

 pair more reddish ; hind femora considerably thickened on outer part, more 

 slender and arcuate toward the base, below with short spines ; hind tibise straight, 

 produced into a small spur below. Wings nearly hyaline, with dark veins, nar- 

 rowly clouded with In-own along the costa. 



One specimen, Arizona (Professor Comstock, No. 152). 



Ectypiis linibatus n. sp. 



Female. — Clay yellow; thorax reddish; veins of the wings clouded with 

 brown ; abdomen light-yellow fasciate. Length 22 mm. 



Antennae orange-red, the third joint, except its base, blackish ; lamella shorter 

 than the third joint, tapering on the middle to the base. Head red, in the mid- 

 dle of the front blackish; the sides of the front, the face, and the posterior orbits 

 thickly light yellowish gray pollinose ; pile sparse, silky white ; proboscis short, 

 blackish, labellse broad. Thorax opaque reddish cinnamon-brown, the humeri and 

 pleuraj more yellowish ; dorsum with two stripes of sparse white pubescence : 

 just above and below the dorso-pleural suture two spots of whitish pollen and 

 another on the sterno-pleurre. Abdomen luteous yellow, shining, the first four 

 segments with a rather broad posterior light yellow margin ; terminal segments 

 cylindi-ical, the ovipositor with about twelve short rays ; legs yellow through- 

 out; hind femora elongate, only slightly thickened, gently arcuate, with two 

 rows of spines below ; hind tibiae straight, not produced into a spur at the tip. 

 Wings with broad, dark brown clouds on the veins. 



One specimen, Arizona (Professor Comstock, No. 149). This spe- 

 cies agrees throughout in its general characters with the description 

 and figures given by Gerstaecker (Stett. Ent. Zeit. 1868) of his genus 

 Edypus, and, so far as the female characters indicate, evidently 

 belongs to this genus. The tyj^e and only other known species of the 

 genus, so far as I am aware, is E. pinguls Gerst., from Africa.
