176 ENTOMOLOGICAL NEWS. [April, '13 



clasp segment suhapical, short, obese, apically with a heavy, chitinous 

 spur and internally with a group of thick, long setae; dorsal plate di- 

 vided, the lobes roundly triangular ; ventral plate short, tapering broadly 

 to a broad, slightly emarginate setose apex. Harpes rather long, slen- 

 der, somewhat spoon-shaped, well chitinized. 



Female. Length 1.5 mm. Antennae (presumably female), third and 

 fourth segments free, the fifth with a stem about one-fifth the length 

 of the cylindric basal enlargement, which latter has a length two-and- 

 one-fourth times its diameter, a rudimentary basal whorl of setae and 

 low apparently anastomosing circumfili, these latter suggesting some- 

 what the condition seen in the male antennae of Asphondylia. Ovi- 

 positor short, fleshy, with a length less than one-fourth that of the 

 abdomen, the terminal segment being stout and terminating in rather 

 broad, triangular lobes. Other characters, so far as observed, practi- 

 cally as in the male. 



Type Cecid 32378. 



The specimens from which the above description was drafted 

 are badly broken and our only excuse for the characterization 

 is that the biological data may be preserved. The species is so 

 peculiar that there should be no difficulty in identifying the 

 midge from the data we have given. It is possible that this 

 species represents a new genus in the Asphondyliariae, some- 

 thing which can be determined best after perfect specimens of 

 both sexes are available. 



A New Species of Dixa from Chile (Dixidae, Dipt.). 



By CHARLES P. ALEXANDER, Ithaca, N. Y.* 



In a collection of Neotropical crane-flies belonging to the 

 Hungarian National Museum and kindly sent to me for deter- 

 mination by Dr. Kertesz, there was included a species of Dixa 

 from Chile. This is the first record for a member of this 

 family of flies from south of the Equator. Of the 21 described 

 species, 12 are European, 8 are American and i is Chinese. Of 

 the American species all are Nearctic with the exception of 

 the widely distributed Dixa clavulus Willistony which was de- 

 scribed from the Island of St. Vincent. Dr. Johannsen has 

 examined this specimen and states that it is very different from
