and ending at ajiical fourth, curving anteriorly towards the second carina and 

 joining here a short, but rather broad, oblique streak which extends from the 

 shoulder backwards ; this streak is the anterior remnant of a second vitta, of which 

 an elongate postmedian spot is the posterior remnant ; this latter is either 

 contiguous with the first vitta or separate from it.

3. Callichroma rhodoscelis spec nov. 



S- A small species. Bluish green, purplish on occiput, at the base of the 

 pronotum, and the lateral edge and apex of the elytra; pubescence golden; basal half 

 of all femora, and the greater part of the fore- and midtibiae rufous. Head coarsely 

 punctured, frons rather long and somewhat rugate, not regularly plicate. Scape of 

 antenna rather dispersedly punctured. Prothorax as long as the elytra are broad 

 at base, transversely jjlicate from apex to beyond middle, farther back the plication 

 becoming feeble and disappearing at the sides ; the ridges are concentrical on disc 

 before middle in two places, as in C. a/rum ; lateral spine prominent, conical. 

 Scutellum and suture of elytra more densely pubescent. Elytra rugosely punctured ; 

 shoulders ])rominent, smooth, with single small punctures. 



Underside of head irregularly plicate, transversely and densely jmnctured. 

 Pubescence of breast and abdomen dense. Prosternum minutely and very densely 

 shagreened, not distinctly plicate. Punctures of fore- and midfemora dispersed, very 

 few large punctures on upperside ; carina of fore- and midtibiae prominent.

4. Xylotrechus aedon spec. nov. 



3. Rufous brown, legs paler ; pubescence pale golden, silky. Frons tricarinate.

 the basal constriction, on disc a mesial line and a broader lateral irregular vitta 

 pubescent, indistinct. Elytra obviously narrowing behind, extreme base (iucl. of

 aj)ex, indistinct ; aj)ex obliquely truncate, external angle strongly, sutnral angle
