Thorax with scattered foveate and finer punctures crowded at the sides 

 behind and a deep fovea on each side and a well-marked basal de- 

 pression, also a faint double depression anteriorly, the sides at the 

 middle show a broad very stout upcurved, obtuse tooth and 

 all four corners well developed angles, the rear setose ; a glance 

 of green shows here and there on the aeneous part of the thorax. 

 Elytra slightly compressed at the middle, parallel, bright metallic, 

 bronze, with 2 foveate depressions on each side, a subbasal, ante- 

 median and a sublateral, median; impressed with large punctures ar- 

 ranged in nearly regular rows up to and including the fifth, after 

 which they are broken and confused about the middle, the confusion 

 coinciding with the two foveate depressions. The rufous inside shows 

 here and there faint touches of greenish color. 



Type Maroka, British New Guinea, 3500 ft. X, '95 (An-

 Guinea, the others coming from Queensland. 



M. submetallicus Jac. (types in my coll.) shows thoracic 

 angles before and behind as above described, though not as 

 large, and the elytra show similar depressions, though not 

 as deep, and the elytral punctuation is very much less marked 

 in submetalliciis than in aenescens. 



Synoptical Table of the North American Species of 

 the Dipterous Genus Sympycnus, with the 



description of a new Species. 

 By M. C. VAN DUZEE, Buffalo, New York. 



Two species of Sympycnus came to me determined as Neu- 

 rigona while I was working up that genus ; one I am describ- 

 ing below as S. clavatus, and the other was our common 

 eastern form S. lincatus Loew. The following characters 

 separate Sympycnus from related genera. 



Eyes of the male contiguous below the antennae or nearly 

 so; first joint of the antennae without hairs above, and the 

 second joint without a thumb-like projection along the inner 

 side of the third joint. Abdomen of the male with six visible 

 segments besides the hypopygium ; hypopygium short, not ex- 

 tending forward under the venter, and with small append-
