EUACANTHUS INTERRUPTUS, Linnaeus. 

 Euacanihiis inierruptHS, Linx.eus, Fauna Siiec, p. 889 • 



Six specimens of two varieties are present. 



EUACANTHUS ANGUSTATUS, new species. 



Much narrower and longer than the preceding species, and with 

 fully developed wing-covers. The head is also less indented and 

 slightly narrower. Color black; head with a large yellow, angular 

 spot next the eye and extending behind connects with the same color 

 on the cheeks, each side of middle behind is round fossa, followed 

 exteriorly by a shallow groove; face yellow, with tliree black spots 

 above, surmounted by a yellow dot in the black of the vertex, and on 

 the middle a black dot. Pronotum sublunate, polished, partly bordered 

 each side before by a yellow band. Scntellum with a yellow sub tri- 

 angular spot at base, and the acute tip also yellow. Wing-covers long 

 and narrow, black, polished, bordered with pale yellow. Middle of 

 sternum with a black spot. Venter narrowly yellow on the sutures of 

 the segments. 



Length to tip of hemelytra, 6^-7 mm.; width of pronotum, Ih mm. 



Type.—^o. 3129, U.S.N.M. 



Eight specimens are present. Possibly this is the macropterous 

 form of the preceding, but it offers a few structural points of difference 

 therefrom. 



TETTIGONIA VIRIDIS, Linnaeus. 



Teti\gon\a virldis, Linx.eus, Fauna Suec, p. 89G. 



Thirteen specimens of the common form are present in the collection, 

 although some are of large size. 



TETTIGONIA FERRUGINEA, Fabricius. 



Tetfigonia ferniriinca, Fabricius, Entom. Syst., p. 32, No. 22. — Signoret, Ann. 

 Soc. Ent. Frame, 1863, p. 676, pi. xxii, fig. 5. 



Fifteen sj)ecimens, almost exactly alike, contribute a showy element 

 to the collection. The name given to this species by Fabricius is unfor- 

 tunate, since the insect, instead of being ferruginous, is usually of a 

 bright orange yellow, with black markings.
