IVOTOXUS Geoff. 



IV. delicatllS n. sp. — Form slender, ratlier convex. Pale testaceous, 

 head and prothorax slightly darker, on the disk of each elytron near the 

 middle and very near the base there is a rounded suffused spot of slightly 

 darker tint; also at or just behind the middle a transverse very narrow baud 

 of fuscous tint, bent forward near the suture so that the anterior point on 

 the suture is distinctly in front of the middle, also at the apical fifth a 

 narrow band of the same color, somewhat broader and much more regular, 

 slightly bent forward toward the elytra, apices pale, under surface very pale 

 reddish llavate, legs same, antennae slightly darker ; pubescence fine, very 

 dense and recumbent with a few erect scattered setae. Head slightly longer 

 than wide, very broadly sinuate behind ; eyes moderate, very coarsely granu- 

 late, three-fourths their own length in advance of the posterior angles ; 

 interocular surface broadly and strongly impressed, rather densely pubes- 

 cent, coarsely alutaceous or reticulate ; supra-ocular carinae very fine rather 

 feebly convergent anteriorly; antennae longer than the head and prothorax 

 together, second joint rather robust, one-half longer than wide, two-thirds 

 as long as the third, very much shorter than the fourth, outer joints com- 

 pressed. Prothorax very slightly longer than wide ; sides very arcuate 

 anteriorly, straight and moderately convergent posteriorly; disk very con- 

 vex, very finely and feebly punctate, basal groove transversely and poste- 

 riorly angulate, narrow, very strong, not attaining the basal margin ; horn 

 much shorter than the pronotum, narrow, not constricted at base, rather 

 acutely rounded anteriorly, edge reflexed, finely and rather distantly dentate 

 throughout the circumference, crest rather feebly elevated, long, narrow, 

 acute anteriorly where the surface is slightly declivous, edge broken, finely 

 dentate. Elytra at base one-fourth wider than the pronotum, widest slightly 

 behind the middle where it is nearly two-thirds wider than the pronotum ; 

 disk conjointly evenly rounded behind ; inner apical angles narrowly 

 rounded ; rather convex, feebly impressed at the basal third, two and one- 

 third times longer than wide, coarsely closely and evenly punctate ; punc- 

 tures rounded and impressed. Legs slender ; first joint of tlie posterior 

 tarsi very slightly longer than the remainder. 



Male. — Terminal segment narrowly truncate at tip ; surface feebly reflexed 

 but scarcely impressed. 



Female. — First segment relatively a little shorter ; terminal obtusely acumi- 

 nate at tip ; first joint of the posterior tarsi much longer than the remainder ; 

 thoracic horn much wider, strongly dilated toward tip and constricted at 

 base. Length 2.8 mm. 



Atlantic City and Cape May, N. J., 3. 



A very fine distinct little species which apparently belongs imme- 

 diately after b/fasciatns in the catalogue ; it is not rare along the 

 seacoast of New Jersey. The bands of tlie elytra are very narrow 

 and often very pale in color.
