270 PHYTOPHAGA.—SUPPLEMENT. 
Evidently allied to H. opulenta, Horn; the latter, however, is described as having 
fulvous antenne, a very wide thorax, and finely but not closely punctured elytra. The 
Nicaraguan specimens are of a bluish tint, and they have the elytra not quite so 
strongly punctured as in the Chiriqui examples. H. elongata, which also has fulvous 
legs, differs from H. fulvipes by the nearly quadrate thorax, and by the distinct punc- 
tuation at the apex of the elytra. 
28. Haltica gracilis. 
Oblong, dark violaceous-blue, the antenne black ; thorax impunctate, the basal margin obsoletely depressed in 
the middle and at the sides; elytra closely and finely punctured, the sides longitudinally costate in the 
female; underside black; the extreme base of the coxe and the knees fulvous. 
Length 1-12 line. 
Head with the usual deep punctures near the eyes, the frontal elevations strongly raised, the carina acute ; 
antenne with the terminal joints scarcely thickened, the third joint slightly longer than the second ; 
thorax a little widened at the base, the sides nearly straight, the anterior angles oblique, the surface 
impunctate, the usual sulcus only indicated by a depression at the middle of the basal margin and by 
another on each side; scutellum large, triangular, black; elytra with a feeble depression below the base, 
very finely and closely punctured in rows, the sides with a distinct ridge extending from the shoulder 
almost to the apex in the female, simple in the male. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This small species may be known by the thorax being impunctate and without a 
well-defined groove. The laterally costate elytra in the female, and the fulvous colour 
of the base of the coxe and knees, will further help to distinguish H. gracilis, which 
seems to vary greatly in size. 
29. Haltica purulensis. 
Black, above metallic blue, the first three joints of the antennw fulvous; thorax impunctate, the sulcus only 
indicated at the base by a depression; elytra extremely minutely punctured, the base somewhat swollen. 
Length 1 line. 
Hab. GuateMata, Purula in Vera Paz (Champion). 
Rather smaller than H. gracilis; the antenne much more slender, with the third and 
following joints more elongate, and the basal three joints fulvous; the thorax with the 
usual transverse groove represented by a faint depression at the middle of the basal 
margin; the elytra scarcely perceptibly punctured (even when seen under a strong 
lens), and with the basal portion distinctly raised. 
30. Haltica longicornis. (Tab. XLI. fig. 25, ¢ .) 
Dark violaceous-blue or greenish; the antennew black, as long as or longer than the body in the male, much 
shorter in the female ; thorax closely punctured and finely rugose, the basal sulcus very shallow; elytra 
extremely closely and distinctly punctured, the interstices in the female rugose. 
Length 2-22 lines. 
Head finely rugose at the sides, with a single deep puncture near the eyes, the middle portion smoother and 
triangularly raised; the frontal elevations broad, feebly raised, and somewhat elongate; the clypeus
