9. APLOMYA NEUROTOMAE, new species 



This species resembles to some extent both Aplomya fronto Coquil- 

 lett and A. caesar Aldrich. 



Male (type).— Head with front at narrowest 0.29 head width; 

 frontal row of bristles extending from on a level with a little below 

 base of third antennal segment to three strong reclinate upper front- 

 als on one side and two strong and one weak on other; no small hairs 

 on upper part of parafacial directly below lowest frontals; facial 

 ridge bristly on lowest two-fifths; gena one-sixth eye height; para- 

 frontal, face, gena, and posterior orbit with light-gray, silvery pollen, 

 parafrontal slightly blackish on upper part toward vertex; antenna 

 black, third segment four and one-half times as long as second. 



Thorax shining black covered with gray pollen, marked by five 

 mesonotal vittae ; black scutellum covered with gray pollen except on 

 basal one-fourth, with a pair of discal scutellars; hind tibia ciliate, 

 with one long bristle near middle ; wing grayish hyaline ; third vein 

 with three and four bristles at base; squamae white. 



Abdomen shining black, second to fourth segments silvery-gray 

 pollinose except narrow posterior borders and a dorsal vitta, which

 of second and third antennal segments ; facial ridge bristly from one- 

 third to one-half ; gena varying from one-eighth to one-sixth, usually
