Hab. Norta America, Quebec ®.—MeExico, Venta de Zopilote in Guerrero, Atoyac 
(H. H. Smith). 
Several males, one of them having the abdomen dark red. 
Echinomyia piliventris (p. 34). 
To the localities given, add:—Mexico, Venta de Zopilote, Chilpancingo, Atoyac 
(H. H. Smith). 
The female of this species is now known to me; it has, as usual, a broader front 
and shorter foot-claws and pulvilli, and the front tarsi are not dilated. £. piliventris 
is very like a dark-coloured specimen of LE. robusta, but easily recognizable by the 
thicker palpi and the absence of genal bristles, and in the female by the undilated 
anterior tarsi. 
A badly-preserved female from Northern Yucatan (Gaumer) may perhaps belong to 
this species, though the thorax and scutellum are densely covered with cinereous 
tomentum, and the abdomen is wholly brownish-red with white reflecting spots. 
MICROPALPUS (p. 34). 
Micropalpus fulgens (p. 34). 
To the localities given, add:—-Mexico, Venta de Zopilote, Chilpancingo, Amula, 
Xucumanatlan, Omilteme (H. H. Smith). 
A long series of this species has now been received from Mexico.
