spots, the venation brown, tlie stigma with a large yellowisli 

 streak ; the first branch of the radius longer than the second, the 

 first transverse cubital nervure interstitial with the recurrent 

 nervure. 



Sab. St. Vincent. 



Described from a single specimen, taken at an altitude o£ 

 2000 feet. The species approaches closest to P. tibialis, Hal., 

 but is decidedly different in the venation. 



Ph^notoma humeralis, sp. n. 



S . Length 4 millim. Pale ferruginous, closely, finely punc- 

 tulate ; shoulders, the depressions at sides of scutellum, and apex 

 of metathorax fuscous. Head transverse, the occiput scarcely 

 emarginated. Antennae 24-jointed, acuminated at tips, pale 

 ferruginous, the four or five small apical joints black. Thorax 

 without furrows, the disk flattened. Metathorax with a slight 

 carina on the superior edge of the posterior face, the face itself 

 rugose. Wings hyaline, the venation pale, the costal edge and 

 istigma darker, the latter with a pale streak in the middle ; first 

 branch of radius only half the length of the second, the first 

 transverse cubital nervure interstitial with the recurrent nervure 

 and at the junction very pale. Legs pale. Abdomen of three 

 segments, the last segment the longest. 



Sab. St. Yincent. 



Described from a single specimen. The pale colour, shape of 

 the head, and the shortness of the first branch of the radius 

 readily distinguish the species. 



Ph^notoma meeidionalis, sp. n. 



S . Length 3 to 4 millim. Pale ferruginous or honey-yellow, 

 finely, closely punctulate, with fuscous or black markings on 

 thorax ; the metathorax and upper surface of the abdomen black 

 or fuscous ; sometimes the latter has a rounded yellow discal 

 spot, sometimes it is pale with an irregular, central stripe ; the 

 metathorax usually has two pale spots at base. Head large, 

 transverse, excavated posteriorly, with the stemmaticum black. 

 Antennae pale, multiarticulate. Thorax with the parapsidal 

 furrows obsolete posteriorly before reaching the base of the 

 scutellum. Axillae meeting aa a slender line before the base of 

 the scutellum. Metathorax rugose, with an irregular carina on 

 the superior edge of the posterior face. Legs pale. Wings 

 subbyaline, the venation pale brownish, some of the nervures
