mediate space very naiTOW, the frontal tubercles small, the carina 

 acute, the clypeus triangularly raised ; labrum flavous, as well as 

 the palpi; antennae extending to the middle of the elytra, flavous, 

 the last two joints wanting, the second joint half the length 

 of the third ; thorax twice as bi'oad as long, narrowed to a 

 slight degree anteriorly, the sides straight, the anterior angles 

 oblique, the disc impunctate, flavous ; the basal sulcus very deep, 

 sinuate, and placed rather closely near the basal margin ; scutellum 

 rather broad ; elytra convex, elongate and widened towards the

Hcih. Espirito Santo, Brazil. 



Evidently allied to L. capitata lUig., but rather smaller, more 

 convex, the antennpe and the labrum entirely flavous, the first- 

 named shorter, the eyes still larger, and the elytra reddish-fulvous, 

 not testaceous. 



Lactica rufo-basalis, sp. n. 



Elongate, parallel, flavous ; the antennje (the basal joint 

 excepted) black ; head and thorax reddish, impunctate, the basal 

 sulcus very deep ; elytra impunctate, flavous, the base reddish 

 fulvous ; below and the legs flavous. 



Length 7 millim. 



Head impunctate, i-eddish fulvous, very shining, the frontal 

 tubercles rather obsolete, cai-ina acute and nairow ; eyes large, 

 coarsely granulate, the intermediate space not broader than their 

 diameter ; antennae extending beyond the middle of the elytra, 

 black, the basal joint flavous, the third joint twice as long as the 

 second, but shorter than the fourth jomt ; thorax about one-half 

 broader than long, slightly nan-owed anteriorly, the sides straight, 

 with a rather broad, reflexed margin, the anterior angles oblique, 

 the disc extremely shining, impunctate, the basal sulcus very 

 deep, placed at some distance from the base, the lateral perpen- 

 dicular grooves still deeper ; elyti-a subcylindrical, scarcely 

 widened at the middle, not distinctly punctured but crowded 

 with numerous piceous specks, the basal margin reddish, the rest 

 of the surface flavous, the metatarsus of the posterior legs as 

 long as the following joints together. 



Hah. Tejuca, Brazil. 



This is a large-sized species, of which a single example is in my 

 collection. It is distinguished by the coloration of the head, 

 thorax, and elytra, the flavous legs, and very deep thoracic 

 sulcus. 



Lactica pemorata, sp. n. 



Flavous, elytra rufous, the posterior femora piceous ; head and 

 thorax impunctate, the basal sulcus very deep and sinuate, elytra 

 impunctate. 



Length 2| millim. 



Head impunctate, eyes large, entire, frontal elevations obsolete, 

 carina short, acute ; antennae entirely fulvous, extending beyond
