LACTICA. 277 



16. Lactica antennalis. (Tab. XVI. fig. 11.) 



Elongate, parallel, testaceous below ; breast, abdomen, and terminal joints of the antennae black ; head 

 fulvous ; elytra violaceous, very minutely punctured. 



Length 1J line. 



Head obscure fulvous, broad ; eyes very distant, inner margin near the latter impressed with a few rather 

 deep punctures ; frontal tubercles absent ; antennae more than two thirds the length of the body, obscure 

 fulvous, the four or five terminal joints piceous, fourth joint as long as the second and third joints 

 together ; thorax impunctate, testaceous, the basal sulcation deep ; scutellum of the same colour ; elytra 

 narrowly parallel, without any basal transverse depression, of a dark violaceous blue, very finely punctured 

 wben seen under a strong glass ; underside, with the exception of part of the breast, piceous ; abdomen 

 black ; legs testaceous. 



Hah. Guatemala, Capetillo (Champion). 



I must separate this species, of which I have five specimens for comparison, from the 

 preceding ones similarly coloured, on account of the fulvous head, the long antennae, 

 their colour, and general shape of the insect. 



17. Lactica panamensis. (Tab. XVI. fig. 4.) 



Oblong-ovate, fulvous; antennas (the three basal joints excepted) black; elytra bright metallic green, 

 minutely punctured. 



Length 1| line. 



Vertex of head extremely minutely punctured ; a single fovea is placed close to the inner margin of the eyes ; 

 clypeus strongly raised and somewhat curved, narrowed between the eyes ; antennae nearly as long as 

 the body, black, the first three joints fulvous, the fourth as long as the two preceding joints together; 

 thorax transverse, fulvous, very shining, the sides rounded and slightly narrowed in front, basilar sulcation 

 very deep, slightly sinuate, and terminating at each side at some distance from the lateral margin ; scu- 

 tellum broad, fulvo-piceous ; elytra convex, nearly parallel, the base with a shallow transverse depression, 

 longitudinally sulcate within the humeral callus, disk very minutely and closely punctured; visible only 

 under a strong lens ; a row of deeper punctures extends along the extreme lateral margin ; underside and 

 legs fulvous ; tarsi obscure piceous. 



Hah. Panama, Volcan de Chiriqui (Champion). 



From similarly coloured species the present one may be separated by the small size, 

 the bright metallic green elytra (which have only a slight tint of blue in some speci- 

 mens), and the long antennae. L. dives, Har., is distinguished by the dark violaceous 

 elytra and the different comparative length of the joints of the antennae, being besides 

 of larger size. To judge by the numerous specimens received, the species must be not 

 uncommon in Panama. 



18. Lactica seneipennis. (Tab. XVI. fig. 20.) 



Elongate, parallel, testaceous below ; antennae piceous ; eyes closely approached ; elytra impunctate, metallic 



greenish aeneous. 

 Length l|-2 lines. 

 Head about as broad as long ; eyes very large and prominent, the space dividing them much narrower than 



their diameter in the male, deeply longitudinally foveolate, obscure piceous or fulvous ; carina distinct ; 



penultimate joint of the maxillary palpi elongate, slightly thickened, terminal one acute, short ; antennae
