ERIOCERA.— TIPULA. 13 



N.B. — This species cannot be E. nigra, Walk., because the latter has some yellow at 

 the base of the wings. E. tenebrosa, Walk., from South America, is too badly described 

 for recognition. 



7. Eriocera lessepsi, sp. n., <? . ' 



Metallic blue ; head orange-red ; wings unicolorous, brown. 

 Length 10-12 millim. 



Hab. Panama. 



Front, vertex, and first joint of the antennae orange-red ; the latter has a brown line 

 on the side ; antennae (except the first joint) black, if bent backwards they would reach 

 the root of the wings ; underside of the head brownish. Thorax and coxae deep 

 metallic blue ; abdomen velvety-black, the posterior margins of the segments metallic 

 blue ; the forceps of the male reddish-brown. Wings uniformly brown ; legs black, 

 with slight metallic reflections ; there are four posterior cells ; the venation is the same as 

 in E. hcemorrhoa, only the petiole of the fork which includes the first submarginal cell 

 is not more than half as long as that cell. 



A single male (coll. Bigot). 



N.B. — The described specimen is in bad condition, and, especially the thoracic dorsum, 

 is partly concealed under a patch of dust ; nevertheless there will be no difficulty in 

 recognizing the species. 



TIPULA. 



Tipula, Linnaeus, Syst. Nat. (1735). 



l. Tipula monilifera (?). 



Tipula monilifera, Loew, Linn. Entom. v. p. 404, t. 2. ff. 26, 27 \ 

 Hab. Costa Rica, Irazu (Rogers). — Brazil. 1 . 



I refer, with doubt, to this species a male and a female from Irazu, Costa Rica 

 (Bogers). They agree with Dr. Loew's species from Brazil in the unusual structure of 

 the antennae and, very nearly, in the colouring of the body and wings ; but, besides small 

 discrepancies in the coloration of the body, the wings do not show the longitudinal 

 hyaline band running from the discal cell towards the apex, as figured by Loew; 

 instead of it, there is only a small hyaline spot at the distal end of the first posterior 

 cell, and another at the proximal end of the second. 



A third specimen from the same locality, a male, has the coloration of the wings 

 still more different, although the body seems to be the same. We have here either 

 several closely conflicting species or else a very variable one. 



The specimens are not well preserved enough to make it worth while to draw up a 

 more detailed description. In the Berlin Museum I have seen specimens of the same 

 group determined as T. spilota, Wiedem. (Aussereur. zweifl. Ins. p. 553, ? ; Brazil).
