Subtribe Adelphomyaria 



The division Adelphomyaria, as known, includes but the single genus 

 Adelphomyia Bergroth, a curious genus of small crane-flies which, in the 

 general appearance of the adults, strongly suggest the hexatomine sub- 

 tribe Limnophilaria. The immature stages have not been associated with 

 the adult flies by rearing, and there is, of course, the possibility of a 

 mistaken reference. The immature stages of the insect herein described 

 are easily recognized, however, and, no matter to what group it belongs, 

 it deserves subtribal rank under the Pediciini. 



Genus Adelphomyia Bergroth (Gr. brother + fly) 



1891 Adelphomyia Bergr. Mittheil. Naturf. Ges. Bern, 1890, p. 134. 



Larva (supposition).- Body with pencils of stiff setae, producing a spiny appearance 

 Spiracular disk surrounded by four short lobes which are fringed with exceedingly elongate 

 hairs. Spiracles large, separated by a distance less than the diameter of one. Head cap- 

 sule long and massive, all the plates firmly united except behind. Mandible acutely pointed. 

 Maxilla of two elongate separated lobes. Antenna two-segmented, the terminal segment 

 with three small papillae. Hypopharynx labriform. Mentum completely divided, each 

 half with four teeth, the middle pair on each side the largest (minuta, supposition) or the 

 second from the inside the largest (americana, supposition). 



Pupa (supposition^ . Cephalic crest small, each lobe with three setiferous tubercles. 

 Pronotal breathing horns moderate in length, broadly tipped with light yellow. Mesonotum 

 unarmed. Wing sheaths extending beyond base of third abdominal segment. Leg sheaths 

 extending to beyond base of fifth abdominal segment. Abdominal armature weak, especially 

 on posterior segments. 



Adelphomyia is a small genus of crane-flies, including but four European 

 and three North American species, and a doubtful species from Africa. The
