Gibson accepts hipunctulata Woodworth as a valid species, but 

 the type is merely a female of that author's nigra. As Gibson 

 sinks the latter as a synonym of melanota Spangberg it appears 

 to me that the only course left will be to follow with the female. 

 That nigra is a synonym of melanota I do not doubt, but the 

 female appears to me to be bimaculata Spangberg so that there 

 are some other synonyms involved. The only difference between 

 the male of nigra and a male of melanota which appears to me to 

 warrant their being considered as entitled to separation even as 

 varieties is that the el3'tra of the former are whitish while those 

 of the latter are fuscous. The genitalia are identical in the two 

 forms. The only specimen of melanota before me was named by 

 Dr. E. D. Ball. 



• Four of the males of nigra bear manuscript labels with the 

 word " type " on them, but one specimen so labelled was taken 

 three years after Woodworth's paper was printed, and as all bear 

 the label " det Woodworth '98 " it is obvious that the label in at 

 X least one case is wrong. 



It may be pertinent to draw attention to the fact that in all but 

 one reference Gibson gives 1896 as the date of Woodworth's 

 paper while it really appeared in 1887. 



I have access to a limited amount of material here, but surmise 

 that it may develop bimaculata Spangberg is merely the female of 

 melanota Spangberg. 



Before me there are a number of specimens named bimaculata 

 Woodworth. No specimen of this species bear type labels. The 

 two that are referred to in our species catalogue under the name 

 bim,aculata are females of puncticollis Spangberg, but they do not 

 agree with Woodworth's description. The only specimens named 

 bimaculata by Woodworth which agree with his description are 

 two which I consider referable to citrina Spangberg. We have a 

 series of specimens of this species from Texas and they dififer in 

 no respect from those from Illinois.
