64 Mr. Martin Jacoby's descriptions of some 



Haplosonyx philippinensis, n. sp. 



Rufous; the antennae and the tarsi pale flavous; thorax sparingly 

 punctured, deeply depressed at the sides; elytra finely punctured in 

 irregular rows, the interstices minutely punctate. Length, 5 lines. 



Of uniform reddish colour above, the under side paler ; the head 

 impunctate ; the clypeus strongly raised, triangular ; the apex of the 

 mandibles black ; the antennae extending to half the length of the elyti'a, 

 pale flavous, the basal joint fulvous, the second and third joints short, 

 subequal ; thorax more than twice as broad as long, the sides straight fi-ora 

 the middle to the base, widened and rounded anteriorly, the anterior angles i 

 .obliquely thickened, the posterior ones acute, the disc with a very deep 

 lateral depression or fovea, which also extends downwards to the base, very 

 sparingly and minutely punctured ; scutellum fulvous, smooth ; elytra with 

 the basal portion distinctly raised and bounded by a transverse depression 

 below the base, the disc finely punctured in indistinct double rows, the 

 interstices also minutely punctured ; under side rather pale ; the tibise more 

 flavous, with an obsolete darker stripe at the outer margins ; tarsi flavous. 



Hah. Philippine Islands. 



A single specimen is contained in my collection. 



Platyxantha vakiabilis, n. sp. 



Black ; the head, antennae, thorax, and legs fulvous ; thorax without 

 impressions, impunctate ; elytra very finely punctured or impunctate, 

 fulvous, a broad transverse band at the base and another below the middle, 

 black. 



Var. a. Elytra black, an obscure transverse band at the middle, and 

 the apex broadly fulvous. 



Var. b. Elytra entirely black. 



Var. c. Under side pale fulvous. 



Length, B^ lines. 



(J . Head broad, impunctate, fulvous ; the frontal elevations narrowly 

 transverse, the space between the antennae raised into an acute ridge and 

 terminating in front in a blunt tubercle ; anterior margin of the clypeus 

 concave ; apex of the mandibles black ; antennee extending nearly to the 

 end of the elytra, slender, fulvous or piceous, the first joint very slender and' 

 elongate, stained with black above, the second very short, the third concave 

 at its outer edge, the fourth joint slightly shorter than the preceding one ; 

 thorax slightly broader than long, the base somewhat narrowed, the sides 

 nearly straight, the anterior angles slightly produced, the surface without 

 any depressions, impunctate ; scutellum flavous or black ; elytra not 

 perceptibly punctured, slightly depressed below the base, their epipleui'ae 

 prolonged below the middle ; tibiae unarmed, anterior coxal cavities closed. 



Hah. Java {Fruhstorfer) . 



Evidently a most variable species in regard to colour, not 

 two specimens being alike, and allied to P. clijpeata, Baly, with 

 which it agrees in the smooth, not foveolate or impressed, 

 thorax. I have taken the description from a well-marked 

 specimen, in which the elytra have two transverse black bands 

 of variable shape, the first leaving a narrow space above the 

 shoulder of the fulvous ground colour, and being narrowed at 

 the sides ; the posterior one is of more regular width. In one 

 of the varieties these bands are connected, but interrupted 

 at the middle by some spots of the fulvous ground colour. In
