PHROSINELLA FUMOSA, new species 



Male. — Front at narrowest 0.42 of head width (measurements of 

 four 0.41, 0.42, 0.43, 0.43) ; front golden polhnose, including the vitta 

 which is scarcely distinguishable from the parafrontals; vitta diverg- 

 ing slighlty towards the rear, at level of lowest orbitals, three times 

 width of either parafrontal; ten to twelve bristles in the frontal row; 

 parafrontals sparsely beset with black bristly hairs which extend 

 downward to apex of second antennal joint, and invade the vitta 

 to the extent of several hairs on each side between the frontal rows; 

 facial ridges with two to four small bristly hairs not extending above 

 the lowest fifth; antennae black, extending about seven-eighths dis- 

 tance to vibrissae, apex of second joint rufous, third joint four times 

 length of second; arista thickened on basal three-fifths, length of 

 penultimate joint one and one-half times width; parafacials white 

 pollinose, bare, narrowest at lower corner of eye; in profile, bucca 

 equals one-sixth eye height. Thorax densely gray pollinose with bronze 

 reflections; two narrow vittae between the presutural dorsocentrals, 

 ending at transverse suture; scutellum densely gray pollinose, with 

 conspicuous black spot on each side near base; intermediate marginal 

 bristles larger than the other two equal pairs; preapicals lacking. 

 Abdomen densely gray pollinose, distinctly tinged with bronze; 

 first three segments with one to three obscure spots near the apices, 

 fourth with apical margin subshining black; first and second segments 

 each with a single lateral and one median marginal pair of bristles; 

 third and fourth with marginal rows of ten to twelve. Genitalia 

 black; inner forceps elongate, tapering gradually to slender tips, 

 somewhat flattened laterally, in profile, with a pronounced concavity 

 on the outer margin just beyond the base, and curving slightly for- 

 ward at the tips; outer forceps yellow, nearly as long and somewhat 

 broader at the tips than inner forceps ; penis with membranous hood 

 tapering from a bulbous base to a slender erect process at the pos- 

 terior apical corner, and bearing anteriorly rather coarse conical 

 spines; posterior claspers with a small bristle. Wings subhyaline, 

 with the area limited by small cross-vein, hind cross-vein, apex of 

 fourth and the costal margin, infuscated; hind cross-vein and last 

 two sections of fourth vein with clouded margins; section of fourth 

 vein beyond bend strongly arcuate, frequently bent backward 

 to form an acute angle with preceding section; last section of fifth 

 vein scarcely more than one-third preceding section. Legs black; 

 second joint of fore tarsus with a ventral tuft of long upcurved 

 bristles, cupped when viewed from above; last three joints much 

 reduced and arched above the tuft of bristles, the third broad and
