260 Annals Entomological Society of America [Vol. XIII, 



Habitat: Formosa. Holotype, cf, Koshun, April 25-May 

 25, 1918 (J. Sonan, K. Miyake, M. Yoshino). Paratopotype, 

 cf ; homotypes, 3 specimens in the collection of the British 

 Museum. 



Eriocera lygropis (Greek, "gloomy") is closely allied to 

 E. unicolor de Meijere, of Sumatra and was determined as such 

 by Edwards in his report on Formosan Tipulidae (Annals and 

 Magazine of Natural History, ser. 8, vol. 18, p. 253; 1916). 

 Subsequently Mr. Edwards and the writer have come to doubt 

 that the two species are identical and specimens from the 

 British Museum were sent to Dr. de Meijere by Mr. Edwards 

 for comparison with the type of unicolor. Dr. de Meijere 

 reports as follows: "The most conspicuous difference is that 

 in your species there are broad shining bands on the abdomen, 

 while in mine the abdomen is practically wholly dull black. 

 The thorax of my species is more shining, on the part before the 

 suture there are only three thin dull lines and also the hinder 

 part is more shining. Your species is somewhat larger and the 

 wings are broader, the end of Rs is nearer the wing-apex, the 

 fork of i?2+3 and the discoidal cell are somewhat shorter, the 

 latter more quadrate." I would express my indebtedness to 

 Mr. Edwards and Dr. de Meijere for thus clearing the identity 

 of this large and conspicuous crane-fly. 



Tricyphona Zetterstedt. 

 Tricyphona formosana sp. n. 



General coloration light brown ; legs pale brownish testaceous ; wings 

 subhyaline; vein R^ long, oblique in position; cell 1st M2 open. 



Male — Length about 4 mm.; wing, 5.S mm. 



Rostrum reddish brown; palpi brownish black. Antennse com- 

 paratively short, dark brown,- the first scapal segment obscure brownish 

 yellow; flagellar segments oval. Head light brown, sparsely pruinose. 



Mesonotal praescutum light brown, indistinctly transversely

 somewhat resembling the condition found in T. protea Alex.; r-m 

 inserted at about mid-length of /?4+5; cell 1st Mi open by the atrophy of 

 m; cell Mi present ; basal deflection of Cui inserted on Af .3 about one-half 

 its own length beyond the fork of M.
