INSKCUTOR INSCITO; MENSTRUUS 11 



lobes, one broad squarely ended, with one angle produced, 

 with a series of small hairs on the margin ; lateral lobes much 

 smaller, one with a bent appendage. No core visible. 



There is still another male besides the type, of the same 

 locality and sent at the same time. This is a poorly developed 

 small Lesticocampa species, bred perhaps from the same lot of 

 larvae as Wyeomyia pertinans and preying upon them. From 

 the same locality and at the same time by the same collector 

 Lesticocampa perturbans Williston was sent, and it represents 

 probably a specimen of this species (compare genus Lestico- 

 campa) . 



Dendromyia quasiluteoventralis Theobald. 



Only a female specimen is present without a type label. It 

 differs distinctly from Theobald's description by having white 

 on the mid legs. The locality on the label is New Amsterdam, 

 which is different from the localities mentioned in Theobald's 

 original description. The hind legs of the specimen are lost. 

 It is perhaps Wyeomyia oblita Lutz, but the specimen is too 

 much damaged to be sure. 



Dendromyia luteoventralis Theobald. 



It cannot be placed. The legs are unhanded. The eyes have 

 a continuous white border. Median distinct white line on 

 occiput. Colors of the abdomen separated in a straight line. 

 Scutellum dark. Prothoracic lobes dark, with coppery tips. 

 Proboscis swollen, dark, not white below. Palpi short, dark. 

 Mesonotum dark. Postnotum and clypeus without scales. 



Genus TRIAMYIA Dyar 



Triamyia personata Lutz. 



Dyar supposed already (Itis. Ins. Mens., vii, 121, 1919) that 

 Dendromyia personata Lutz came in his new genus Triamyia. 

 We can confirm this by the examination of a mount of the 

 genitalia of Lutz's species. The side-piece is moderate, 

 attenuated at the apex ; insertion of clasp filament apical. 

 On the side-piece a long ridge of numerous long wavy hairs. 

 Basal lobes setose. Clasp filament slender, long, a triangular
