A NEW SPECIES OF PHORID.E FROM NEW ENGLAND. 



By Charles T. Brues.

In a small collection of New England Phoridse recently given 

 to me for identification by Mr. C. W. Johnson, I have found one 

 large and conspicuous species of the genus Chsetoneurophora 1 

 which appears to be undescribed. 



Chaetoneurophora aureiventris sp. now 



Length 5 mm. Head and thorax black, abdomen reddish orange, legs honey yel- 

 low, wings tinged with brown. Head small, its bristles very large and stout; front 

 less than twice as broad as high, its surface grayish pollinose, with an impressed 

 median line extending from the anterior margin to near the antennal tubercle and 

 widening out above into a depression which fills out the space between the median 

 bristles of the sub-ocellar row, and extends above the antennae as a fine, impressed 

 line; supra-antennal pair of bristles reclinate, stout, approximate at base; row above 

 of four nearly equidistant bristles forming an arcuate line curved down medially; 

 sub-ocellar row of four equidistant bristles in a straight line, the lateral ones very 

 near the eye margin. Antenna? oval, moderately large, orange-red, with sub- 

 dorsal piceous, pubescent arista as long as the width of the head. Post-ocular 

 cilia very large and stout, strongest just above the middle of the eye; cheeks each 

 w r ith a very long rnacrocheeta at lower angle and a bunch of several short bristles 

 above next to the insertion of the antenna. Palpi orange-red, of ordinary size, beset 

 below with very short bristles with several long ones in addition near apex. Meso- 

 notum and scutellum black, the humeral angles fuscous; one pair of dorsocentral 

 macrochaetae and four equally stout scutellar bristles; scutellum transverse, nearly 

 twice as broad as long. Pleurae piceous, lighter below, the propleura fuscous, with 

 a tuft of bristles above the coxa, and elsewhere sparsely clothed with short bristly 

 hairs, several of which at the upper angle are decidedly larger. Mesopleura not 

 bristly. Abdomen reddish orange, the segments subequal, except the sixth which 

 is much elongated. External genitalia piceous, and first segment infuscated above 

 except near the middle; second segment with a tuft of small black bristles on each 

 side, slightly elongated, but not very strongly so. Sides and venter of abdomen 

 entirely orange-yellow. Pleurae black or fuscous, the amount of black varying 

 from none to nearly the entire pleura. Mesopleura not bristly above. Coxae and 

 legs brownish yellow or testaceous, hind femora slender, none of the tarsi 

 thickened. Fore tibia with a single bristle at the middle on the outer edge; 

 middle tibia with three bristles, one at end of basal fourth on front side, one 

 at end of basal third on outer side and one on front side just before tip,
