pentagonal area ; the postocular area three times as wide as long ; 

 the front between the eyes and the walls of the pentagonal area 

 broadly and rather deeply hollowed out ; the portion of the antennal 

 furrows on the vertex wedge-shaped, extending from the lateral 

 ocelli to the occiput, the end adjacent to the lateral ocelli widest; 

 the interocu4ar furrow wanting ; the antennae with the first and 

 second segments together two-thirds the length of the third, the 

 third segment one and one-half times as long as the fourth, the 

 fourth and fifth subequal,' the sixth shorter than the fifth and sub- 

 equal to the seventh, eighth and ninth, the ninth obliquely rounded 

 at apex ; the dorsum of the thorax polished and finely sericeous ; 

 the wings slightly infuscated, the veins and the stigma fuscous ; the 

 front wings with the free part of R 4 twice as long as the free 

 part of R 5 , the free part of R 4 and the radial cross-vein straight ; 

 the greatest length of the cell R 4 only slightly greater than the great- 

 est length of the cell R 5 ; the legs finely sericeous, the posterior 

 metatarsus shorter than all the following segments together, the 

 second segment slightly longer than the third, the third twice as 

 long as the fourth ; the abdomen very sparsely pubescent ; the 

 saw-guides concave above and gradually, convexly rounded below 

 to a bluntly rounded point at apex. Length, 4 mm. Habitat : 

 Florida. Mrs. Annie Trumbull Slosson, collector .. liturata, n. sp. 

 Front wings with the cell R t not twice as wide at the R 4 end as at the 

 R 5 end, usually subequal 6. 



6. Front wings with the free part of R + strongly bowed and the radial 

 cross-vein straight ; body black, with the legs below the knees, except 

 the apical half of the posterior tibia; and more or less of their tarsi, 

 white ; the walls of the pentagonal area fairly distinct, the ridges 

 fine, enlarged at their ventral ends and forming a fairly distinct 

 frontal crest, the ocellar basin about as broad as long, the Y-shaped 

 furrow above the median ocellus sharp and deep, a narrow, flattened 

 area along the crest of its walls, the walls of the pentagonal area 

 continued almost to the bases of the antennae, slightly concave in- 

 wardly on top, the enlarged ventral ends of the walls not united at 

 middle, broken at middle by a shallow but rather broad notch ; the 

 median fovea deep, V-shaped, the base of the V against the frontal 

 crest and each arm extending to an antennal fovea, the tubercular
