further along the interstices than on the costae. Eather more 

 than a third of the elytra in their middle is straw-yellow. The 

 apical black is also rather irregidar on its basal side. This insect 

 mimics very closely the Fhotimis described hereafter as P. notatus, 

 and is probably to be found in company with it. 

 Two examples.

The body and head are black, with the exception of the fifth 

 and sixth segments in the male and the middle of these segments 

 in the female, which are white, and that the tips of the trochanters 

 and base of the femora and the basal joint of antennae are pale. 

 The thorax is ochraceous ; in some examples the subdiaphanous 

 part above the eyes appears as a dark spot taking the form of a 

 bisinuate line, and in some there are two very obscure spots on 

 the middle of the base. The scutellum is yellow, the praescutellar 

 part fuscous. The form of the thorax is broadly semi- elliptical, 

 slightly ogival in the males, and the sides and front are rather 

 coarsely punctured. The elytra are pitchy black, with the entire 

 sides and suture yellow, thickly punctured, and with two obsolete 

 costEe. This insect is allied to, and of the same size and form as, 

 A. lepidum (Biol. C.-Am. 1. c. p. 54). It differs in the wholly 

 yellow sides and suture of the elytra, and in the thorax being 

 much less conspicuously marked. 



The males scarcely differ from the females, except in the size of 

 the eyes and more eburated luminous segments of the abdomen. 



A large number of specimens were captured.
