GONOSPA.—PHALERIA. 217 
agrees in the structure of the meso- and metasternum, &c., it will be known by its 
indistinct clypeal membrane, differently shaped head, rounded eyes, six-jointed antennal 
club, &c. Gonospa resembles a genus of Chrysomelide, e.g. Phedon. The elytra bear 
just within the reflexed lateral margins a series of coarse irregular impressions, as in 
many Carabide. Same habits as Hapsida. 
1. Gonospa pheedonoides. (Tab. IX. fig. 29, 3.) 
Short oval, convex, above metallic bronzy cupreous, shining. Head coarsely and rather sparingly punctured, 
the epistoma indistinctly defined; prothorax strongly transverse, the apex broadly but feebly emarginate, 
widest at the base, narrowing a little anteriorly, the sides slightly rounded before the middle, thence 
straight to the base, the surface rather coarsely but not closely punctured, the disc smoother ; elytra with 
regular rows of rather fine distantly placed shallow punctures, and an interrupted marginal row of 
irregular, coarsish impressions (placed just within the reflexed margins), the interstices flat and exceedingly 
finely and sparingly punctured, the base shallowly impressed on each side in the middle; antenns with 
the four basal joints and the extreme apex red, the rest black; legs dark reddish-brown or black, the 
knees and tarsi more or less red; inner side of the posterior tibie in the male feebly emarginate before 
the apex; beneath dark reddish-brown, shining, very finely and sparingly punctured. 
Length 33-43 millim. (¢ 9.) 
Hab. Panama, Bugaba (Champion). 
Two examples. 
Group TRACHYSCELIDES. 
This group contains only the well-known genus Phaleria (represented on the coasts 
of almost every part of the world, except Australia, and also in many oceanic islands), 
and Bycrea and Scaptes. Trachyscelis and Anemia, represented in North America, as 
well as in Europe, have not yet been received from our country.

Numerous species of this genus have been described from Europe, Madeira, the Cape 
Verd and Canary Islands, Africa, Madagascar, North and South America, the Antilles, 
Galapagos Islands, &c. Nine species have been described from North America; one 
only from Central America, whence we now add eight others. The different species 
are found beneath decaying seaweed or at the roots of herbage on sandy sea-coasts, and 
are apparently not very widely distributed ; one new species described here is, however, 
found both on the Atlantic and Pacific coasts. Some of the species inhabiting 
North and South America have the margins of the thorax and elytra fringed with 
hairs.
