to omit the species from our list, but recently Mr. Ulke has received 

 a specimen from Wisconsin. The species is doubtless an introduced 

 one, and not a member of the sub-arctic fauna common to both 

 continents. 



Doubtful Species. 



OalerucR fibiilata [Germar] ; testacea, autennis apice pectoreqne fuscis, 

 elytris linea rectaiigiila baseos maciilaque aute apicem nigris. Habitat iu America 

 septentrional i. 



Affinis G. quadrimacnlafie, caput flavo-testaceuni, oculis autennanmique apice 

 nigris. Thorax siibquadratus, niarginatus, punctiilatus flavo-testaceus. Coleop- 

 tera thorace latiora, api(!e obtuse rotundata. obloiigo-quadrata, punctata testacea ; 

 linea utrinque basali in humero raraum rectangulum emittente; macula magna 

 aute apicem nigris. Corpus subtus testaceum, pectore fusco. 



This description seeins to apply very well to some of the varieties 

 of the male of Cerotoma frifurcata, and the name would have been 

 placed in synonymy with that did not certain remarks of Dr. Le- 

 Conte (Proc Acad. 1865, p. 209) require explanation. 



There exists in the LeOonte cabinet a specimen which is undoubt- 

 edly Galeruca quadrimaculata Oliv., and which came originally from 

 the Melsheimer cabinet, and to this Dr. LeConte has attached the 

 name fibulatus, and applied the remarks above cited. The specimen 

 has remained unique for at least fifty years. That Olivier might 

 have been in error in his locality is suggested by Dr. LeConte, but 

 it is also possible that Melsheimer may have been in error as other 

 Javanese insects were in his cabinet (see Pachyurgu>i cere^is Mels. = 

 Encyalesthes hrevicornis Motsch. from Java, etc.). Galeruca quadri- 

 notata Oliv. seems to have been omitted in the " Catalogus." 



<5. (lorsata [Say]. — Pa.le yellowsh, elytra blue, with a yellow outer margin 

 and tip. Inhabits Arkausa. 



Body pale yellowish ; head black on the vertex ; antennse black brown ; thorax 

 immaculate; punctures obsolete; scutel blackish bronze; elytra irregularly 

 punctured, greenish blue; exterior margin and tip yellow; an indented, abbre- 

 viated line on the basal middle; feet with blackish line above. Length one- 

 fourth of an inch. 



Found on the banks of the Arkansa above the Verdigris. This 

 insect, if it be a Chrysomelidae at all, has not been identified. 



d. jailthiiia Lee, Ann. Lye. 1, p. 173, is Haltica chalybea Illig. 



Supplementary Notes. 

 The following notes have been prepared as a sui)plement to pre- 

 ceding papers on the Chrysomelidie v/ith the view of correcting
