hina No records are available, however, to indicate what species of 

 plants are thus frequented. The larvae live in decaying wood Ihe 

 only species whose immature stages are known is the genotype Elephanto- 

 myia westwoodi. The literature on the immature stages of this group 

 of flies is very limited, the only record being the unknown Limnobnne 

 No 1 of Malloch (1915-17 b:235-236), who gives a good description ot 

 the larva. The pupa is here described and figured for the first time.

Elephantomyia westwoodi is a rather common fly in eastern North 

 America The adults are usually found in cool, shaded woods and may 

 be swept from vegetation in these localities. The larva lives m deca>ang 

 wood as is shown by the three records avaUable to the writer. 



The larvae were found by Shannon in a very wet, rotten, willow log 

 lying near the tidal flat above the brewery at Rosslyn, Virgmia, on May 

 21 1913 About eight larvae were found, well scattered thru the log. 

 They were very active in their movements and were very beautiful m 

 life being of a deep golden yellow color. These larvae were placed m 

 rearing, and adults issued on May 27 and 29 and June 5 and 7, indicating 

 a pupal duration of a week or slightly less. Larvae were found m thxs 

 log also on November 23, 1912, and at that time they were ahnost grown, 

 being about one-half inch in length. This shows that the species spends 

 the winter as almost fully grown larvae. ^ 



Johnson found these larvae near Edge Hill, Pennsylvania, on June 

 25 1899 and on May 25, 1905, in a log, just beneath the bark. Larvae 

 and pupae obtained by him were in the material studied in the preparation 



of this paper. , j i „+ 



Malloch found a single larva of this species m a much decayed log at 

 White Heath, Illinois, on April 30, 1916 (Malloch, 1915-17 b: 236). 



Larva.— Length, 10-13.4 mm. 

 Diameter, 1.2-1.3 mm. 



Coloration of body, a deep saturated golden yellow thruout. 



Body moderately elongated, terete, relatively slender, tapermg gradually toward either end 

 but more noticeabfy and abruptly toward anterior end (Plate LXXX 432) ; the three horac. 

 segments gradually increasing in size from the prothorac.c backward. Abdommal segmen^
