178 MR. MARTIN JACOBY ON NEW SPECIES [Mal\ 4, 



oblique, the basal sulcus very obsolete as well as the perpendicular 

 grooves, the disc impunctate, flavous ; scutellum flavous.; elytra 

 extremely closely and minutely punctured, convex, black, sur- 

 rounded by a pale flavous margin which widens rather at the 

 ■ apex ; below and the legs pale testaceous, the middle of the breast 

 sometimes stained with black. 



Hah. Peru. 



There are five specimens of this small species in my collection. 

 Of these two represent the variety which has the base of the 

 elytra black only and the rest of the disc faintly stained with 

 fuscous, so that the pale latei-al margins are still plainly distinct. 



c. Elytra entirely pale-coloured. 



Lactica paraguayensis, sp. n. 



Flavous ; antennae robust, black, the basal three joints flavous ; 

 thorax strongly transverse, the basal sulcus rather shallow ; 

 elytra parallel, flavous, impunctate, the apex of the femora 

 piceous, the tibise and tarsi black. 



Leng-th 5 millim. 



Of elongate, not very convex shape ; the head impunctate with 

 the exception of a single deep puncture near the eyes, the latter 

 not large, frontal elevations only indicated, the carina very broad 

 and convex, clypeus likewise strongly raised ; labrum flavous, apex 

 of the mandibles and the palpi piceous ; antennae comparatively 

 robust, black, the lower three joints flavous, stained with piceous 

 above, the second and third joints small, of equal length, the 

 following joints rather dilated ; thorax more than twice as broad 

 as long, the sides straight, obliquely narrowed anteriorly, the 

 anterior angles obliquely produced, the basal sulcus shallow, 

 placed close to the base, the lateral perpendicular grooves very 

 deep, the surface entirely impunctate; scutellum rather broad, 

 triangular ; elytra impunctate. 



Hah. Paraguay. 



This Lactica, of which a single specimen is contained in my 

 collection, may be distinguished by the rather robust antenna?, 

 the rather small-sized and widely separated eyes, and especially by 

 the very transversely shaped thorax and its produced and oblique 

 anterior angles. It differs in this respect from any of the many 

 similarly coloured species of the genus. 



Lactica apicipes, sp. n. 



Elongate, moderately convex, testaceous, the antennae (the 

 basal joint excepted), the apex of the tibiae, and the tarsi black ; 

 thorax impunctate, transverse sulcus shallow, perpendicular grooves 

 deep ; elytra extremely minutely punctured. 



Length 4-5 millim. 



Of elongate, parallel, and moderately convex shape, the head 

 impunctate, the fi'ontal elevations obsolete, carina broad ; eyes very
