larvae of Sdara longipes Meig. Toward the end of May only a few larvae 

 were left, and these appeared fully grown but were not carried over into 

 the pupal condition, which is still unknown. 



Larva.- Length when fully grown, 7.4 mm. 



Color light reddish yellow, contents of alimentary tract showing thru body. Body terete 

 (Plate LXXXII, 443), consisting of twelve segments, there being, besides the head, three 

 thoracic and nine abdominal segments; last segment wedge-shaped (Plate LXXXII, 446 

 and 447), obliquely truncated so that the surface slopes from behind upward. Two spir- 

 acles on this oblique surface, with a paler brown, pincer-shaped mark between. Mouth 

 parts powerfully constructed. Mandible (Plate LXXXII, 444), produced into a long apical 

 point; near midlength on inner edge of mandible a deep incision, distad of this about five 

 teeth, basad of it three teeth. Labrum quadrangular, with two lateral points on anterior part. 

 Men turn projecting outward as a cuticular rounded lobe. (Brauer shows two other append- 

 ages which are toothed on the outer face [Plate LXXXII, 445, of this paper] ; these probably 

 represent part of the mentum, but from Brauer's figures they would appear to lie above 

 the labrum.)

Larva. Form terete. Segments of body just before sutures with transverse rows of stiff 

 hairs; abdominal segments 5 to 8 on ventral surface with a mouthlike depression surrounded 

 by long, stiff hairs. Spiracular disk surrounded by four lobes, ventral pair the longest, 

 each of the latter bearing at its tip a single very long bristle. Spiracles moderately large, 

 located at base of lateral lobes. Head capsule very long and narrow, the four plates very 

 elongated. Mandible very small. Maxillary palpi short. Esophageal region surrounded 

 by chitinized plates which are conspicuously obliquely ridged. Body of larva covered with 

 numerous long, appressed hairs, producing a satiny appearance. Coloration saturated 

 golden yellow. 



Pupa. Form slender. A small crest on vertex above eyes. Eyes very large, globular, 

 narrowly separated on frontal and vertical regions, ilostral sheath very elongated; palpi 

 recurved against it. Antennal sheaths lying across eye. Head and thorax with setiferous 

 tubercles. Abdomen with rudimentary lateral spiracles. 



Elephantomyia is a small genus of crane-flies including about a dozen 

 described living species. These are found in widely separated regions 

 of the world, there being about four in the East Indies, five in Africa, 

 and two in North America, one of which has been recorded also from 

 Europe. The genus is found fossil in the Baltic amber. The adult 

 flies are remarkable for their very elongated rostra, and undoubtedly 

 they feed on the nectar of tubular flowers as in the related genus Toxor-
