DIPLECTROIDES.—VASACES. 127 
opaque, the head and prothorax not so dull. Head (including the eyes) about as wide as the prothorax 
in the female, broader in the male, densely and rather coarsely punctured, longitudinally depressed 
between the eyes; the latter black, exceedingly large and narrowly separated in the male, smaller and 
more distant in the female; antenne very long in both sexes, still longer in the male, black or blackish- 
brown; prothorax about as long as broad, the sides moderately rounded in front and converging behind, 
the base and apex somewhat strongly margined, the former indistinctly emarginate in the middle, the 
hind angles prominent, the disc with a large triangular or V-shaped depression in front, irregularly trans- 
versely depressed behind, and often with a smooth median ridge or channel, the surface finely and densely 
punctured (in some examples less closely so); elytra very elongate, very densely and minutely punctured, 
the apices separately rounded ; beneath very densely punctured, thickly pubescent, testaceous, the venter, 
and sometimes the coxe, more or less suffused with violaceous; legs blackish-violaceous, the femora often 
in great part testaceous. 
3. Fifth ventral segment very deeply triangularly emarginate; the sixth with two very large spoon-shaped 
pieces, these latter hairy within. 
Length 13-19 millim. (¢ 9.) 
flab. Mexico, Misantla (Hége); Guatemaza, Sinanja, Sabo, Purula, and San Geré- 
nimo in Vera Paz (Champion), Vera Paz (Conradt). 
Ten male and three female examples; the single specimen ( 2 ) from Mexico has 
the head and elytra violaceous. The localities for this species are all upon the Atlantic 
slope. 
Our figure is taken from a typical male specimen from Sinanja. 
2. Diplectroides flavicollis. (Tab. VI. fig. 6, 2.) 
Elongate, black or brownish-black, the head and scutellum brownish in one example, the prothorax flavous’ 
the upper surface finely pubescent, the head and prothorax shining, the elytra opaque. Head very finely 
and closely punctured, the eyes ( 2 ) moderately large and rather widely separated ; antenne ( 9 ) blackish- 
brown or brown, moderately long ; prothorax ( 2 ) rather broader than long, moderately rounded at the sides 
in front and constricted behind, the base and apex somewhat strongly margined, the hind angles promi- 
nent, the disc a little flattened, transversely depressed on each side in front and also about the middle, 
depressed in the centre at the base, and with traces of a smooth median ridge, the surface very minutely, 
shallowly, and closely punctured ; elytra shorter than in D. longicornis, scabrous, the apices obtuse ; beneath, 
the prothorax excepted, black or brownish, pubescent, finely scabrous ; legs black or brownish. 
Length 143-163 millim. (9). 
Hab. Mexico, Peras, Parada (Sallé). 
Two female examples. Differs from the corresponding sex of D. longicornis in the 
smaller and more widely separated eyes, much more finely punctured head and thorax, 
the latter broader than long, shorter and stouter antennex, shorter and more scabrous 
elytra, shorter legs, and different colour. 
VASACES. 
Mandibles bifid; last joint of the maxillary palpi long, elongate-triangular (V. wneipennis, V. sordidus) or 
cultriform with the outer edge sinuate (V. costatus), that of the labial palpi subtriangular; mentum 
about twice as broad as long; eyes somewhat coarsely granulated, rather small, oblique, very widely sepa- 
rated in both sexes, rather distant from the point of insertion of the antenne, and, at most, very slightly 
emarginate ; head about as broad as the prothorax, a little broader in the male, rather produced in front ; 
antenne filiform, long, slender, 11-jointed in both sexes—1 stout or moderately stout, about as long as 3, 
2 about half the length of 3 (in V. sordidus, 2 , nearly as long as it), 3 shorter than 4, the succeeding
