"H. testaceo affinis, sed minor, magis depressus, regulariter ovatus, thorace scabro-punetato, scutello rufo, elytris 

 hand flavo-marginatis, femoribus apiee extus, tibiis tarsisque nigris. L. c. 5|-6| lin." 



Hab. Beitish Hondueas (Blancaneaux) ; Guatemala 1 , Cubilguitz in Vera Paz 

 (Champion) ; Nicaeagua (Salle), Santo Domingo in Chontales (Janson \ Belt) ; Costa 

 Kica 1 , Cache (Bogers) ; Panama, Bugaba, Volcan de Chiriqui, Tole (Champion). 



The numerous specimens now before me show that this species is not so nearly allied 

 to H. testaceus as the above diagnosis would lead one to suppose. It is much more 

 difficult to separate it satisfactorily from H. umbonatus, Lac, and H. hepaticus, Crotch. 

 The colour is very variable, it being sometimes as dark as that of E. umbonatus ; but 

 the thorax has never more than faint shades in the place of the vittee, and the scutellum 

 is not dark as in H. umbonatus. The antennae, however, in H. confusus are entirely 

 black at their apices. Crotch alludes x to specimens from Venezuela which have the 

 femora entirely yellow ; these are not in his collection, and they may be specifically 

 distinct. A specimen from Bugaba is figured.

A great number of specimens of this insect have been sent ; these show considerable 

 disparity in size, and some difference in form and sculpture. The largest examples are 

 those from Costa Rica, several of these being 14 millim. long, and the smallest are some 

 from Capetillo (8 millim.). These latter very much resemble H. jansoni, but may be 

 known from it by being less convex and with the margins of the elytra a little more 

 reflexed, and also by the interstices of the striae being flat and not so deeply and less 

 thickly punctured. 



Many of the larger examples have the elytra with an expanded production at the 

 tips, but I cannot ascertain that this is a sexual distinction. 



Lacordaire l also gives Mexico as a locality, but I have no doubt that his specimens 

 from that country belong to the following species. 



A specimen from Capetillo is figured.
