straight at the base, rounded in front ; anterior margin deeply con- 

 cave, posterior one strongly convex ; disk distantly, sides very 

 closely and deeply punctured, especially near the anterior angles. 

 Scuteilum metallic green or brass-coloured. Elytra convex, with a 

 deep fovea at the lateral margin below the humeral callus, and a 

 more shallow transverse depression surrounding the fovea ; surface 

 of each elytron with ten regular rows of deep punctures, the first of 

 which extends to only one third the length of the elytra ; these 

 punctures diminish in depth near the apex, and partly unite at the 

 same place ; interstices perfectly smooth. Legs fulvous, with a 

 greenish aeneous hue. 



Collected by Mr. D'Albertis. Three specimens in my collection.

13. HoMOPHCETA militaris, sp. nov. 



Elongate, widened behind, convex. Black ; head and upper parts

Hah. Zapote, Guatemala. 



Head longer than broad, rather flat, with a few distinct punctures 

 across the middle and round the inner orbits of the eyes, yellowish 

 white ; the encarpae and the parts of the mouth as well as the palpi 

 piceous ; antennae black, all the joints, with the exception of the 

 second, which is short, slender, and of nearly equal length. Sides 

 of the thorax nearly straight ; the anterior angles slightly thickened 

 and reaching to the middle of the eyes, but not produced in shape 

 of a tooth ; surface impunctate. Scuteilum smooth. Elytra a little 

 wider at the base than the thorax, distinctly widened posteriorly, 

 the humeral callus but slightly depressed within ; surface impunc- 

 tate or very finely punctured, only visible under a strong glass ; a 

 large round spot at the base and another more transversely shaped 

 near the apex of each elytron of a black or dark violaceous colour, 

 the ground-colour being either entirely yellowish white or changing 

 into bright rufous along the sutural and lateral margins, the former 

 having this colour generally widened in the middle and at the apex. 

 Underside and legs black, closely but finely covered with yellowish 

 hairs.

 Champion. 



This handsome species is almost identical in coloration with the 

 Lactica macula, Fabr., from which it may be at once distinguished 

 by the want of the thoracic transverse depression pecuhar to all the 

 species of the genus Lactica. In those specimens which are marked 

 with the rufous colour the latter generally predominates at the thorax 

 as well, so as to leave only the anterior angles of a lighter shade.
