142 BROOKLYN MUSEUM SCIENCE BULLETIN 3. 3. 
Newfoundland: Stephenville, July (Engelhardt) ; Miquelon (Hardy, in 
coll. Fairmaire of Mus. Paris). 
Specimens of this species in Mr. Wallis' collection are labelled "on 
flowers of Caltha palustris (Mrs. Mulligan)." 
var. FLAViPENNis Mannerheim. 
Differs from typical germari in having the prothorax and elytra, 
or only the elytra flavous, the prothorax in the latter metallic but the 
anterior and posterior angles, base above and below and a spot near 
anterior coxae more or less flavous. 
Alaska: Sitka (coll. of Leconte and Brit. Museum); Metlakatla, June 
(Kinkaid, Nat. Mus.). 
British Columbia: "B.C." (Wickham) ; Bon Accord (Knab coll.) ; "B. C." 
(Taylor in coll. Wallis). 
Oregon: Dilley (Leng coll.). 
The males have the prothorax and elytra flavous and the females 
only the elytra, the latter sex have the prothorax largely metallic, that 
is, in the few specimens which I have seen. 
Specimens with flavous or rufous elytra or with entirely pale upper 
surface occur frequently in the true Donacias but not in any European 
nor American species of the sub-genus Plateumaris except in germari. 
It is on account of this unusual color variation that I restore flavipennis 
as a western color variety of germari. 
D. germari was wrongly considered to be the same as Jemoralis 
Kirby, which is synonymous with metallica Ahr. as already pointed out 
above in the remarks following the description of the latter species. As 
remarked under metallica, Dr. Leconte's male and female of Jemoralis 
belong to two species, the female is metallica and the male is germari. 
Following these in his collection are two specimens from Sitka labelled 
germari and two specimens from the same locality labelled flavipennis. 
The specimens, judging from the labels, were undoubtedly sent to Dr. 
Leconte by Count Mannerheim and possibly belonged to the series from 
which he described germari and flavipennis. Crotch, working on the 
North American ChrysQmelidae, accepts Dr. Leconte's identification of 
Jemoralis, but apparently compared the Sitka specimens only with the 
male and finding them identical placed germari as synonym of Jemoralis. 
D. aurijer and dives of Leconte are not synonymous with pnsilla but are 
the same as germari. The aurijer var. of Leconte's revision is a new 
species. My serricauda is also a synonym of germari. 
D. germari has the prothorax distinctly alutaceous, the punctures 
shallow and rarely very dense, generally the impressed median line
