LACTICA. 259 
limited at the sides by a deep longitudinal groove; scutellum broad, impunctate ; elytra elongate, nearly 
parallel, the shoulders prominent, the surface only visibly punctured when seen under a very strong lens ; 
underside and legs entirely testaceous. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Larger and of a more obscure testaceous colour than L. uniformis ; the eyes more 
widely separated ; the antenne unicolorous; the thorax much more transverse and its 
sides more rounded. ; 
Lactica scutellaris (p. 273). 
To the Mexican localities given, add :—Colima city, Tapachula in Chiapas (Hoge), 
Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith). 
Dr. Horn in his “Synopsis of the Halticini of Boreal America” (Trans. Am. Ent. 
Soc. xvi. p. 231) remarks that LZ. scutellaris would be better placed in the genus 
Haltica, and that it is congeneric (and probably also specifically identical) with #. rufa, 
Ilig. I cannot agree with this opinion; moreover, the present species was not 
described by myself in this work, as stated by Dr. Horn, but by Olivier, and at greater 
length by von Harold. The last-mentioned author also places the species in Lactica, 
although the thoracic depression is not so well marked as usual ; but this is frequently 
the case in other members of the genus. In the broad (not acutely raised) clypeus 
L. scutellaris agrees entirely with the present genus. As regards H. rufa, Dr. Horn 
describes the third joint of the antenne as distinctly longer than the fourth, and the 
entire antenne as piceous; in L. scwtellaris the third and fourth joints are equal or 
nearly so, and the basal two joints are rufous. With scarcely an exception, all the 
species of the genus Haltica have metallic blue or green elytra and a narrow thoracic 
groove ; it is probable that H. rufa is a true Lactica. 
Lactica minuta (p. 274). 
To the localities given, add :—Mzexico, Teapa in Tabasco (7. H. Smith). 
Lactica cupreata (p. 281). 
To the locality Mexico, add :—Yolotepec, La Parada (Sallé). 
The two additional specimens contained in the Sallé collection are more than double 
the size of the type, and they belong doubtless to the female sex; in one of them the 
elytra are minutely punctured. 
 Dactica frontalis (p. 283).
