A NEW GENUS AND TWO NEW SPECIES OF CHLOROPID/E 47 



Legs yellow, normal, no bristles present, the surfaces with short, pale hairs. 

 Wings clear ; veins yellow ; auxiliary vein indistinct ; first costal division 

 over two-thirds as long as second, second slightly over twice as long as 

 third ; outer portions of third and fourth veins subparallel, only divergent 

 at extreme apices ; outer cross vein oblique ; last section of fifth vein dis- 

 tinctly longer than penultimate section of fourth. Halteres pale yellow. 



Length, 1 - 1 . 75 mm. 



Type: Cat. No. 15653, U. S. Nat. Mus. 



Type locality : Biscajme Bay, Florida (Mrs. A. T. Slosson) . 



Paratypes : Male and female, Atlantic Beach, Florida (Mrs. A. T. 

 Slosson) ; one female, Riverton, New Jersey (no collector's name). 



The male is similar In most respects to the female, but the frons is 

 parallel-sided, the surface hairs on frons are pale, and the third antenna! 

 joint is yellow. 



The specimen mentioned above from New Jersey was standing in col- 

 lection as Siphonella pumilionis Bjerkander, from which it is quite dis- 

 tinct. Along with this specimen wzis one from Biscayne Bay which is 

 not the seune species and clearly belongs to Siphonella. The record of 

 Siphonella pumilionis in Smith's list of Diptera of New Jersey is based 

 on the specimen above mentioned ; thus the record is an error and the 

 species probably does not occur in this country. Eugaurax resembles 

 Siphonella but may be distinguished by the bristling of the mesonotum 

 and the form of the proboscis, which is not so elongate nor so distinctly 

 geniculated as in that genus. 



Botanobia (Oscinis) halterata, new species. 



Male : Frons opaque brown, paler anteriorly, surface covered with scat- 

 tered, fine, pale hairs, the base of each of which is set in a distinct punc- 

 ture ; frontal triangle distinct, glossy black, reaching over two-thirds to ante- 

 rior margin of frons, ocelli in an equilateral triangle ; width of frons a little 

 over one-third the head width, its sides parallel ; eyes hairy ; antennae 

 reddish yellow, brownish above on third joint, in size small, third joint 

 disk-like ; airista very short, barely longer than length of antennae, brown 

 in color, distinctly swollen at the base, slightly pubescent ; face black- 

 brown, concave in profile, keel indistinct ; cheeks narrow, black, marginal 

 hairs rather numerous though weak ; proboscis and palpi yellow, the for- 

 mer with apex bent back, but the form not as in Siphonella ; paJpi with 

 distinct though not conspicuous bristles. Mesonotum glossy black ; disk
