Black, the basal joints of the antennæ and the thorax flavous, 
the latter very minutely punctured, elytra closely punctured and 
finely rugose, black. 
* Length 2 1/2 lines. 
‘ Of rather flattened and posteriorly slightly dilated shape, the

metatarsus which agrees better with Zyperus; the transverse 
thorax however and other details suggest the present genus as a 
more appropriate place. 
Rupilia ruficollis Clark. 
I have more than a dozen specimens of this species before me 
which may be either referred to this or the other species Æ. viridi- 
ænea Clark. since the distinguishing characters are to be found 
partly in one or the other specimen and I very much doubt the 
specific distinction of the two insects. The emargination of the 
anterior and posterior margin of the thorax which Clark gives as 
one of the specific characters is present or absent in the different 
individuals as well as the angulate lateral margin, both characters 
differ greatly. All the specimens have the middle of the thoraeic 
disc with a broad dark violaceous band (answering to Clark’s des-
