interest and greatest importance. From a scientific standpoint 

 it is a necessity, and the Academy is to be congratulated upon 

 having a man so well able to do it as Mr. Fuchs. His work will 

 not only benefit present students, but will form a basis upon 

 which future study of the species now arranged may rest. 



No further business being presented the meeting adjourned to

Perdita macniigera n. sp. ^f. — Length 5 mm., pale primrose-yellow 

 with black markings. Head fairly large, subquadrate, broader than 

 long ; cheeks unarmed, with a beard of white hairs beneath ; eyes pale 

 pea-green ; antennae yellow beneath, black above ; head yellow with 

 these black markings, — the usual anteorbital dots, a large irregularly 

 square black patch above each antennae, sending a line from its inner 

 upper angle to the middle ocellus, a patch connecting the ocelli, an 

 obliquely placed large oval spot, touching and sending a very narrow line 

 along the orbit, barely separate from the lateral ocelli, and the black 

 occipital region. Thorax yellow with these black markings, — a trans- 

 verse mark on collar, a small mark on tubercles and a small mark just 

 below, a large basal patch on pleura and a streak beneath the wings, the 

 mesothorax except the lateral margin and a pair of longitudinal yellow 

 stripes, the scutellum except the hind margin irregularly, the postscu- 

 tellum, and the dorsum of metathorax except a large yellow patch some- 

 what trifid behind; tubercles colorless with an opaque yellow spot. Wings 

 hyaline, iridescent, nervures brown; stigma very peculiar, its basal portion 

 colorless and hyaline, the rest intense black, forming a large nearly, round 

 spot. Marginal cell rather short, its postigmatal portion much the largest, 

 the substigmatal part very short, owing to the rounded end of the stigma; 

 third discoidal distinct ; second submargmal large, narrowed half or more 

 to marginal. Legs yellow, anterior coxae tufted with white hairs, anterior 

 femora and tibiae with a black stripe behind, middle femora and tibiae 

 similarly striped, and a black spot near end of middle femora in front, 

 hind coxfe with a black dot near apex, hind femora with a broad obligue
