TOXORRHINA. 109 



in Mr. Loew's comparison ; but, as stated above, I have in this respect 

 also confirmed the agreement of Elephantomyia with the fossil species. 



The foregoing examination can, I think, leave no doubt about the generic 

 identity of Eleph. iceshvoodi with the fossil species. Several years ago, I 

 communicated to Mr. Loew specimens of my Zi7e;jAa?iiom^ia for comparison. 

 If he has discovered any difference between them and the fossil species, 

 sufficient to place them in different genera, he will probably mention this 

 difference in his forthcoming work on Amber-diptera. 



1. E. westwoodi 0. S. '^ and 9. — Ochracea, femorum apice fnsco, 

 segmentis abdominis fusco-marginatis ; stigmate alarum infuscato. 



Ochraceous, tip of the femora brown, margins of the abdominal segments 



infuscated ; stigma brownish. Long. corp. 0.3 — 0.35. 

 Syn. Elephantomyia canadensis 0. Sacken (nee Westw.), Proc. Ac. Nat. Sc. 



Phil. 1859, p. 221 ; the synonymy given there has to be 



stricken out. 



Head yellow ; rostrum finely pubescent ; antennas yellowish, 

 with black verticils ; basal joints, especially the second, more or 

 less infuscated. Thorax yellow ; a more or less distinct browm 

 stripe runs along its middle and down the collare ; in some 

 specimens this stripe is obsolete ; halteres pale ; feet yellow ; 

 femora brown at the tip. Abdomen yellow ; posterior margins 

 of the segments brown ; a more or less distinct brown stripe 

 along the middle of the back ; the last segment brown in the 

 male ; forceps tawny. "Wings with a faint brownish tinge ; a 

 slight nebulosity along the apical margin (for more details com- 

 pare the generic character). 



Hab. Trenton Falls, N. Y., where 1 found this species in great 

 numbers. At that time I took it for Limnohiorhynchus cana- 

 densis "Westw., as the description of this species {Ann. Soc. 

 Entom. de Fr. 1835, p. 683) agrees very well with the present 

 one. But Mr. Westwood's species, which I have seen since in 

 his own collection, is a Geranomyia, my G. communis ; the Ele- 

 phantomijia thus proving to be new, I dedicated this remarkable 

 species to the author of an entomological work which is, as yet, 

 without a rival for completeness, excellence of execution, and 

 corresponding usefulness. 



Gen. VIII. TOXORRHIIVA. 



No suhmarginal cell ; a discal cell, and four posterior cells ; no marginal 

 cross-vein. Rostrum very long, longer than head and thorax taken together ;
