(I>) UNRECOGNIZED SPECIES. 



annulalns ISchrank. This European species was credited to our fauna by Osten 

 Sacken. The description agrees fairly well with specimens whicli I have identified 

 as e.rcitanii, Walker, except that in the latter there is no white ring on the femora 

 toward their apices. 



hoseii Desv. Probably a rubbed sjiecimen oi pimgenx. 



nigripes Zett. Black, the legs of the male dark yellow, hairs of pleura of female 

 gray, a band of white scales at base of each segment of her alidomen. 



rubidus Desv. The description Avas apparently founded on a rubbed specimen of 

 Psoroj)hor(i cUidla. 



testuceus v. d. Wulp. Is prol>al>ly a somewhat injured example of ronxohrhma. 



mcidens Thomson. Is evidently a synonym of iiiipigcr Walker. 



higoii Bellardi. According to the figure and description, the bands of black scales 

 are at the hascit of the abdominal segments; in the recognize<l species these bands are 

 always at the ai)i(tes of the segments. In other respects this species must greatly 

 resemble 'ptrngciis. 



cubensis Bigot. Apparently fomidi>(l on a badly rubbed specimen oi pungens. 



frafer Desv. This name was proposed for the Cnle.r /((.srmAn.s of Wiedemann under 

 the impression that this is not the same sjjecies as the one described by Fabricius 

 under the same name. It seems quite certain, however, that the word "proboscis" 

 m Fabricius' description was simply a lapsus for " palpi," and with this emendation 

 the two descriptions agree verj' well. 



mexicrma Bellardi. Is evidently a synonym ol poslicalns. 



provocans Walker. Is jtrobably a synonym of slimulanfi. In some specimens of 

 this species the light color at the bases of the tarsal joints is very indistinct. 



territans Walker. Is apparently a synonym of puugeug.
