segments four and five subequal, three slightly longer than 

 four; wings hyaline, veins black, costa and stigma rufous. 

 Length lo mm. 



Habitat: Ithaca, New York. Nq. 8.46-1. 



This species is related to niellina Nort in the coloration of its 

 body. 



Tenthredo smectica n. sp. — Female. Body black with the 

 following parts rufous : antennae, occipital and vertical orbits, 

 extending slightly onto frontal orbits, tegulas, legs except proxi- 

 mal portion of procoxse and exposed surfaces of mesocoxse 

 and metacoxse and dorsal surface of metafemora, and abdo- 

 men, including saw-guides, beyond the basal plates ; following 

 parts yellowish white : clypeus, labrum, triangular spot on 

 supraclypeal area, genal orbits, ventral half of mesal orbits, 

 collar, spot above metacoxas, and spot on sides of basal plates ; 

 clypeus narrowly roundly emarginate ; antennae with fifth seg- 

 ment slightly longer than fourth and third about twice as long 

 as fourth ; head finely punctulate, occipital furrows obscure, 

 ocellar basin distinct but not strongly depressed, rounded ridge 

 extending from each antacoria to and bearing a lateral ocellus ; 

 notum and pleurae dull with fine close punctulations ; wings 

 hyaline, with scattered black spinulse, costa and stigma rufous, 

 radius and distal veins black, others rufous. Length 9 mm. 



Habitat: Ithaca, New York. No. 8-ii-2(?)-2. 



While the coloration of the abdomen is very dififerent, this 

 species is related to neoslossonice MacG. 



Macrophya flaccida n. sp. — Female. Body black with the 

 following parts white : clypeus, labrum except a broad X-shaped 

 mark at middle, spot on proximal end of mandible, line on col- 

 lar and tegulae, line on coxae, broadest on metacoxae, trochanters 

 in part, distal three-fourths of cephalic surface of profemora, 

 distal one-third of cephalic surface of mesofemora, ring on 

 proximal end and spot on distal end of cephalic surface of 

 metafemora, cephalic surface of protibiae and mesotibiae, long 

 oblique spot on dorsal surface of metatibiae, and a ring on 

 proximal segment of tarsi ; antennae with third segment as long 

 as the fourth and fifth together ; clypeus emarginate, emargina- 

 tion broadly rounded ; median fovea wanting ; occipital fur- 

 rows f ovea-like ; head uniformly punctulate, without impunc- 

 tate areas ; postocellar area semicircular, broader than long ; 

 median and lateral areas of mesonotum finely punctate, nieso- 

 scutellum coarsely punctate ; mesopleurae uniformly finely
