60 Psyche [April 



Lactica dilatipes sp. nov. 



Small, oblong, light straw- yellow, antennae, except the base, most 

 of the tibae and tarsi and a common triangular spot on the base of 

 the elytra, dark piceous, hind tibia of $ abruptly dilated, inside, 

 near the tip (like some species of Colaspis). 



5 5 39, Salinas Beni E. (Stuart), length 3>4-4 mm. 



Head with a broad, smooth front, with a few fine punctures, 

 antennse relatively stout, reaching the middle of the elytra, second 

 joint nearly equal to the third, thorax with nearly straight sides 

 very finely punctulate, sulci well marked, especially the lateral; 

 elytra, smooth, shining, very minutely punctulate, basal depression 

 slight, the dark spot does not cover the scutel, but touches the base 

 in either side, running round under the shoulder, and a straight 

 line across the middle ; distinguished from sellata by the light legs 

 and dilated S tibia; the punctuation of the 5 is stronger than 

 the S. 



Lactica seminigra Jac. P. Z. S. p. 176, is a preoccupied name 



and should be changed to Eosenbergi. The $ hind tibia is di- 



tinctly curved and has a large spur-like process on the inside 



middle, like calcarata 111. In thoracica Jac. what I take to be the 



$ has a well marked dilation of the hind tibia close to the tip. 



The general shape of the body and the absence or otherwise of 

 the ocular sulcus may be hereafter an aid in the future arrange- 

 ment or division of the species of this perplexing group.
