on the middle. ‘The sutural stria of the elytra is distinct and extends to the apex; the 
other striae are formed by more or less distinctly separated punctures, and become very 
fragmentary on the apical part. One specimen. 
3. Thione championi, sp.n. (Tab. XVI. fig. 6.) 
Subcylindricus, castaneus, nitidus ; antennis pedibusque flavis ; capite prothoraceque parce subtiliter striolato- 
punctatis, illo anterius longius furcato, per dimidiam longitudinem suleato; elytris striatis, striis e punctis 
elongatis compositis. 
Long. 4-5 millim. 
Hab. Guatemata, Cubilguitz and Panima in Vera Paz, El Tumbador, Mirandilla, 
Zapote, Torola (Champion); Panama, Volcan de Chiriqui, Bugaba ( Champion). 
Very similar to T. cephalotes, but differing as follows :—The form is more elongate, 
the head being so long that it appears entirely disproportionate to the prothorax; the 
epistomal processes are longer, and between them there is a broad groove that extends 
backwards, becoming gradually more obsolete, for quite half the length of the head ; 
the strie are more distinct than in 7. cephalotes. 
We have received a small series of this species; at first I thought it might be the 
other sex of TZ. cephalotes, but this does not, after examination, seem to me very 
probable. 
Subfam. SILVANINAE. 
As this subfamily is usually defined by the closure of the anterior acetabula and by 
the tarsi being said to be simple and 5-jointed, and as I do not find these characters 
adequate, it is necessary to make a remark as to its definition. 
The acetabula are closed in such a manner as to render support to the coxe from 
the mesosternum unnecessary, and the prothorax is therefore usually less accurately 
co-adapted with the mesothorax, so that the closure of the acetabula is quite visible ; 
whereas in the Lwmophlai it becomes only evident when the mesosternum is forcibly 
sundered from the prosternum. 
The structure of the tarsi differs from that of the Lemophlwi inasmuch as the 
fourth joint is here subject to a great reduction, while the basal joints become more or 
less co-adapted and clothed with pubescence beneath. ‘The first joint is subject to 
great reduction in size, as it is in Lewmophiei. In many cases the second and third 
joints of the tarsi form free lobes. This structure is found even in some species of 
Silvanus. I consequently place Telephanus in this subfamily, following in this respect 
the example of Erichson.
