48 Psyche [April 



and the fourth about equal, thorax with nearly straight sides and 

 finely punctuate surface, the usual sulci both deep, straight and 

 well defined, elytra very finely and inconspicuously punctulate, 

 and a very obsolete basal depression : the extreme bases of the 

 femora somewhat rufous. 



Lactica limbatus sp. nov. 



Ovate, small, pale straw yellow, labrum, antennae (except the 

 base), vertex and neck, and all the edges of the elytra (including 

 the basal and sutural), very dark reddish, piceous black. 



$ and 9 Porto Velho Eio Madeira, Brabil (Mann and Baker), 

 length 2>4-3 mm. 



Head finely punctured on the face, very sparsely on vertex, 

 thickly in the ocular sulcus, antennae 2/3 as long as body, dilute 

 rufous at base, joints 2, 3, 4, increasingly long, thorax with nearly 

 straight sides, surface very finely iJuuctulate, transverse sulcus 

 fairly well marked, the cut-off at the ends as usual better defined 

 and deeper, scutellum pitchy, elytra thickly and finely punctuate, 

 without basal depression, the disk of each elytron of a pale straw 

 color forming a regular oblong spot from base to apex, but not in 

 any place attaining the edges, body below and legs uniformly pale. 

 The elytral markings easily distinguish this form, 



Lactica bakeri sp. nov. 



Small, elongate j^arallel, anterior face, antenme, thorax and legs 

 pale flavous, tinged (especially the latter) with rufous, rear of 

 head, neck and elytra dark violet, body below greenish-black. 



5 examples, Porto Velho, Eio Madeira, Brazil (]\Iann and 

 Beker), length 2^-3>^ mm. 



Mouth parts, and antennae exteriorly, darkened with rufous, ver- 

 tex with scattered punctures, sulcus of eye more thickly punctate; 

 antennse reaching a little below the middle of elytra, joints rather 

 stout and flattened, the apex of each joint with stiff hairs, thorax 

 with slightly rounded sides, a few fine punctures on the disk, usual 

 sulci, prominent, deep and straight, elytra parallel, without basal 

 depression sparsely punctulate. The Mexican species hidalgopnsis 

 Jac. has the same coloration of the elytra but has the head and body
