addition to the pair of prothoracic air-nipples, — for instance 

 P. fusca and the species figured by Curtis, P. auriculata 

 (both exhibited) ; but more species are possessors of the nieso- 

 pleural pair of appendages alone. The two species last named 

 differ in the shape of their thoracic appendages now under 

 consideration : the male P.fasca has short, chitinous, slightly 

 curved prothoracic air-nipples, and short Dipple-like meso- 

 pleural appendages that spread a dense epaulet-like tuft of 

 hair ; while P. auriculata has slender club-shaped whitish 

 prothoracic air-nipples, and meso-pleural tentacles that are 

 clad with silky hair and are capable of great extension. 



But in the majority of species furnished with this kind of 

 tracheate appendages issuing from the meso-thorax, those of 

 the prothorax are absent ; and some have appendages of the 

 sac form, others of the tentacular form. Among the exhibits, 

 Ulomyia Juligiuusa, Pericoma iiubila and trivialis are ex- 

 ponents of the short, nipple-like, erectile, sac-shaped meso- 

 pleural type of appendage seen in P. fitaca; while Pericoiua 

 palustris, mutua and the nameless species from the Schwarz- 

 wald, together with P. cognata which was not exhibited, have 

 the tentacular type of meso-pleural appendage seen in P. 

 auriculata.
