2. Tachy 



N 



>■ 



Hab. North America 1 .— Mexico, Cordova (Salle), Vera Cruz (Edge) ; Guatemala 



sar the city, Aceytuno, San Geronimo (Champion). 



Mexican and Guatemalan specimens agree closely with an example from Kern Co., 

 California, collected by Morrison. They belong to the pale form of the species, with 

 opalescent lustre on the elytra, strongest on a vaguely limited dusky patch about the 



• middle

 Oblongo-ovatus, castaneus (elytris subopalescentibus), antennis, palpis pedibusque pallide fulvis ; foveis 

 frontalibus latis (interspatio frontali sat angusto et convexo) ; thorace transverso, lato, convexo, lateribus 

 valde areuatis, postice paullo angustato, angulis posticis obtusis sed distinctis, foveis basalibus latis, 

 sulculoque basali acute insculpto, flexuoso; elytris quam in T. corusco minus depressis, striis 3-4

 pallide fulvis ; foveis frontalibus latis (interspatio frontali sat angusto et convexo) ; thorace transverso, 

 postice paullo angustato, angulis posticis paullo obtusis sed distinctis, elevatis, margine laterali (prsecipue 

 postice) sat explanato-reflexo ; elytris latius ovatis, striis duabus suturalibus f ortiter impressis, 3 a indi-

Hab. Panama, Volcan de Chiriqui, 2000 to 3000 feet (Champion). 



Extremely near T. castaneicolor, and scarcely differing either in colour or sculpture. 

 In form of body, however, it is so conspicuously broader, more oval, and larger, that, 

 added to the perceptibly thicker antennae and strongly impressed first and second 

 elytra! striae, I think it must be held to be a distinct species.
