 Hah. Guatemala, Zapote \ Pantaleon {Champion) ; Costa Eica (coll. Jacoby). 



The description of this species gives the thorax as finely but distinctly punctured ; 

 this is a mistake, as a closer examination proves to me ; the surface may be described 

 as being almost impunctate (under a very strong lens some minute punctures can be 

 seen). I look upon one specimen figured (25) as a variety, as it was obtained at the 

 same locality, and I have some intermediate degrees of coloration before me; a 

 constant character in (E. salvini seems to be the black scutellar spot, which in three 

 specimens is shaped as the figure 24 shows, while in others it is rounded and more 

 transverse ; in these forms the shoulder spot is wanting, and the two posterior spots 

 are united; in no specimen, however, that I have seen does the basal spot extend 

 further than the figure represents. The legs are dark brown in one specimen only ; in 

 the others the four anterior ones are nearly black, the base of the femora only being 

 fulvous.

In plainly marked specimens of this species the elytra have a black square patch 

 enclosing two testaceous round spots at their anterior half; in a variety these spots are 

 enlarged, reducing the black portion to narrow transverse and longitudinal bands ; in 

 another variety the black predominates so as to surround a single pale spot below 

 the base ; lastly all the black portion is reduced to two spots at the base and a short 

 transverse stripe at the middle; this latter variety resembles greatly (E. humeralis, 

 Fabr., but in that species there is never (as far as I have noticed) a black spot at the 

 middle of the basal margin of the elytra, a constant character in all the specimens of (E. 

 transversalis and its varieties. 



47. (Edionychis tenuicincta. (Tab. XXIV. fig. 22.) 



Testaceous; antennae obscure fuscous; head and thorax impunctate; elytra very closely punctured, the 

 extreme basal margin, a narrow transverse band behind the middle, and a spot near the scutellum, black. 



Length 2-3 lines. 



Eyes large, the space dividing them not broader than their diameter ; fourth joint of the antennas slightly 

 larger than the third, the five lower and one or two apical joints testaceous, the intermediate ones fuscous • 

 thorax with the lateral margins nearly straight, the anterior angles not produced, the posterior mar°in 

 quite straight, the surface impunctate ; elytra a little widened towards the middle, of a very slightly con- 

 vex shape, the transverse basal and posterior bands extremely narrow, the former extending as far as the
