CERAMBYCHXE 357 



brunneo-pubescent and extending nearly to basal third of the pro- 

 thorax, the latter two-fifths longer than wide, with the sides oblique 

 before the middle, the apex four-fifths as wide as the base; surface 

 evenly convex, feebly so medially, the flanks even and with two white 

 lines, the lower having a minute tubercle near the base; scutellum 

 white, equilatero-triangular; elytra only feebly inflated behind, at 

 two-thirds from the base barely a fourth wider, the sides thence very 

 gradually arcuato-convergent to the rather narrow apex, which is 

 angularly emarginate, the lobes obtusely rounded, with the dorsal 

 impression very elongate; surface evenly convex, with very irregular 

 clustered brownish vestiture, at many points showing the irregular 

 geminate series of moderate punctures and with a white double vitta 

 near inner third, much and very irregularly interrupted almost as 

 in texana, forming two parallel successions of short white lines; 

 abdomen coming very far from attaining the elytral tips, with the 

 fifth segment in the example at hand small, scarcely more than half as 

 long as the fourth and broadly sinuate at tip. Length (cf) 9.6 mm. ; 



width 1.2 mm. Florida (east coast) stolata Newm. 



Form very much more slender but evidently less slender than suturalis, the 

 size much smaller than in stolata; vestiture nearly similar, the ceph- 

 alic punctures where visible much smaller and sparser than in stolata 

 as above identified; vertex before the eyes somewhat longer than 

 wide; antennae much more slender, not quite as long as the body, 

 the scape nearly similar; prothorax narrower, only very feebly 

 narrowed at apex, two-fifths longer than wide and with a broad 

 shallow median sulcus not attaining base or apex, the flanks with a 

 white line, below which the vestiture is much confused; scutellum 

 white, smaller and narrower, slightly elongate; elytra more inflated 

 posteriorly, at two-thirds from the base fully two-fifths wider, the 

 sides thence very evenly and gradually arcuate and converging to 

 the very small, broadly rounded tips, which are separated by a very 

 minute angular emargination, the dorsal impression longer than wide 

 but small in size; surface with confused brownish and white, moder- 

 ately dense vestiture, sparser near the suture, where the close series 

 of strong punctures are in great part exposed, the white and denser 

 vestiture more abundant and longitudinal basally and laterally but, 

 behind the middle near inner third, forming short and widely sepa- 

 rated lines; fifth ventral in the type small, half as long as the fourth, 

 transverse, sinuate medially at tip, the latter more narrowed than 

 in the above assumed representative of stolata. Length 6.7 mm.; 

 width 0.7 mm. Florida (Palm Beach) pertenuis n. sp. 



The identification of sex in Spalacopsis proper is much less certain 

 than in the subgenus Euthuorus, and I am not sure that the above 

 determinations are always correct. My representative of stolata 

 was taken possibly near Palm Beach and I have endeavored to 

 prove that pertenuis is the male of it, but without success, as they 

 are so remarkably different in the type of modification at the elytral
