34 Psyche [April 



segments four and five subequal, three distinctly longer than four 

 and not as long as four and five together ; head with a convex ridge 

 between antennal furrows; ocellar and interocellar furrows obso- 

 lete; mesonotum polished, mesoscutellum with caudal half punc- 

 tured; saw-guides with dorsal margin concave, ventral margin con- 

 vex, converging toward bluntly rounded distal end; wings hyaline, 

 veins, costa, and stigma brownish. Length 6 mm. 



Habitat : Ithaca, N'ew York. No. 119-1-2. 



This species is related to celsa MacG.^ from which it can be dif- 

 ferentiated by lack of ocellar and interocellar furrows. 



Empria carina sp. nov. 



Female. Body black with the following parts white: labrum in 

 part, collar narrowly, tegulas, distal ends of femora, protibise, meso- 

 tibise, proximal and distal ends of metatibiae, proximal end broader 

 than distal, protarsi, and proximal portion of mesobasitarsi ; cly- 

 peus with a fine mesal ridge and tooth, ventral margin narrow, 

 emargination shallow; antenna? with third and fourth segments 

 subequal, short ; ocellar basin shallow, extending between antacorias 

 and bearing pit-like median fovea and median ocellus, latter 

 bounded by distinct Y-shaped furrow; ocellar and interocellar fur- 

 rows distinct; antennal furrows interrupted near middle; post- 

 ocellar area broader than long; median and lateral lobes of meso- 

 notum polished; mesocutellum finely jDunctate; wings hyaline; 

 veins brownish, costa and stigma infuscated; saw-guides with dor- 

 sal margin straight, ventral margin convex, rapidly converging to 

 obliquely, bluntly pointed distal end. Length 6 mm. 



Habitat: Ithaca, Kew York. No. 107-5-2 and 107-3. 



This species can be separated from cavduca MacG. by the shallow 

 emargination of the clypeus and the form of the median fovea. 



Thrinax pullatus sp. nov. 



Male. Body black with the following parts rufous : collar nar- 

 rowly, trochanters, femora, tibia\ and tarsi except two or three 

 distal segments of the metatarsi ; abdominal terga with caudal por- 

 tion with a narrow linear yellowish or rufous margin; antennae 

 with third and fourth segments subequal ; labrum densely seta- 

 ceous; clypeus bi'oadly, roundly, shallowly emarginate; median
