sutural stria continued to the apex. Beneath the head and prothorax are coloured as 

 above ; the mouth and trophi (except at the tips) are rufous ; the prosternum is very 

 smooth, its process strongly arcuate, the apex being almost vertical and slightly excised, 

 and the sides thickened and raised ; the breast and hind body are piceous, nearly black ; 

 and the apical segment is smooth, sparsely and not strongly punctate. 



Three specimens : these present no sexual mark of distinction, unless the more 

 divaricate apices of the elytra be such. I have adopted the name under which they 

 were separated in Salle's collection.

I am unable to identify this species from the very brief description.

The species thus briefly characterized by Crotch has the head, thorax, body, and legs 

 in part red ; the apical segment of the abdomen is, however, black, and the apical half 

 of the femora, the tibiae in part, and the tarsi, blackish. The antenna? are black, but 

 sometimes the basal six joints are red, and frequently one or two are so. The elytra 

 are steel-blue, with very lightly impressed striae, the striae delicately but closely 

 punctured ; the interstices appear nearly smooth, though usually very finely wrinkled, 

 and occasionally (viz. in the example from San Juan) the multistriate appearance is 

 seen. Two Mexican specimens in Salle's collection have the elytra black with a faint 

 brassy tint, and an example from Panima and another from Colima have the punctures 

 of the striae deep and distinct, but I do not consider these differences of specific value. 

 The apical segment is depressed and pubescent; red at its base, but black in the 

 greater part. 



It is impossible to identify this insect, which has the body red, with either L. simpli- 

 cicollis, Say, or with L. sanguinicollis, Chevr., as both those species are expressly 

 described as having the breast and abdomen black. 



Crotch's type and other specimens of L. cyanipennis were from Chevrolat's collection ; 

 they are labelled as having been collected by Salle.
