No. 2313. NEW SPECIES OF EOCENE INSECTS— COCKERELL. 247 



spots as in living species; abdomen dilute fuscous, pallid basally; 

 tegmina dusky, with two broad hyaline transverse bands, the first 

 consisting of a large subquadrate patch, separated from an elongate 

 mark below it by a dark line, but the second mark more widely 

 separated from a narrow band along the lower m-argin. The sec- 

 ond band, beginning 2 mm. from base of tegrnen, consists of two large 

 elongated patches, separated by a dark bar. There is also an 

 obscure hyaline spot in the costoapic?il region. The insect is re- 

 markably similar to living species, especially perhaps to the Japa- 

 nese E. apicalis (Matsumura).

DIPTERA. 



Family TIPULIDAE. 



CYLINDROTOMA VETERANA, new species. 



Plate 34, fig. 3. 



Wing 9.5 m.m, long; width nearly 3 mm.; discal cell about 1.9 

 mm. long, its apex about 2 mm. from apex of wing. Compared 

 with Needham's figure (after van der Wulp),^ if we make the 

 correction indicated by Brunetti,^ there is very close agreement. 

 The wing is more slender and more pointed apically than in Need- 

 ham's figure of G. distinctissima Meigen; the subcosta runs closer 

 to the costa, being separated by a very fine linear interval; the 

 lower branch of radius (radial sector) comes off before the middle 

 of the wing; the marginal cell is much longer, its length about 

 3.9 mm., and ends about 1.2 mm. beyond level of end of first basal 

 cell; the uppermost branch of media forks exactly as in C. dis- 

 tinctissima, with its upper branch strongly arched at base; the 

 discal cell is longer than in C. distinctissima. The anal angle of the 

 wing is subrectangular, more prominent than in O. distinctissima, 

 approaching the condition of Idioplasta. The apex of the first 

 basal cell is formxed as in the Indian C. quadriceUula Brunetti, not 

 as in C. distinctissima, except that the lower apical face (on discal 

 cell) is at least twice as long as the other, which is not at all the 

 case in the Indian species.
