226 Mr. T. Vernon Wollaston on 
The pale lurid or brownish-testaceous colour, and com- 
paratively coarsely punctured surface, of this Huropean 
Philhydrus (the palpi of which seem to be immaculate) 
will readily distinguish it from the followimg species— 
which (although it varies occasionally into a somewhat 
testaceous hue) is always darker (at times, indeed, being 
nearly black), and much more lightly sculptured. As 
already stated, it was captured by the Messrs. Crotch 
during the summer of 1864 in Gomera. 
Phithydrus politus. 
P. oblongo-ovalis, convexus, nitidus, niger sed in

bus); capite maculis duabus lateralibus ante oculos, an- 
tennis (clavi excepti), palpis (articulo 2do ad basin 
interdum excepto) tarsisque rufo-testaceis; coleopteris

longitudinaliter notatis.
