sap-wood. Its burrow is at this time kept clean, with but a few grains of 

 white excrement clinging to the sides, though afterwards it fills it full of 

 brown excrement, or at least it becomes brown by the moisture. The 

 white, chip-like pieces which I supposed to be pieces of the wood plucked 

 off and the nutriment sucked out of them are really excrement, as I saw 

 it passing from the larva. The pupa is of the usual color and is well rep 

 resented in figure accompanying, its principal characteristic feature being 

 the manner in which the antennae are curled around the legs. 



June i5th. Difficult to breed to the imago, and, after losing dozens, 

 with the best of care, I was rewarded at last with a single perfect specimen. 

 It is the Oberea sckaumii. 



March I5th, 1868. I found larvae still in the trees, and that they live in 

 the tree two years is more than ever evident from the fact that there are 

 always two sizes.

In discussing the note on tegulae and patagia, Mr. Howard 

 said that he had correctly defined these terms in the Century Dic 

 tionary, giving the Kirby and Spence signification to the word 

 patagium as a pronotal sclerite. He also said that Comstock 

 could hardly be said to have fallen into error in reference to these 

 sclerites, since he correctly defines the tegulas and simply adds 

 (what is certainly true) that in descriptive works by lepidopterists 

 these structures are called patagia. 



Mr. Schwarz gave the reason why he was led to refer the Mor- 

 dellistena from the stems of Uniola paniculata to M. splendens 

 instead of M. floridensis. He stated that he had experienced 

 some trouble in getting at the name of this species. By a clerical 

 or typographical error in the table of Mr. J. B. Smith's synopsis 

 of Mordellidae no structural differences (number of tarsal ridges) 

 were given between M. splendens and M.floridensis, but he found 

 that the species from Uniola paniculata agreed perfectly with 

 the type specimen of M. splendens in the Smith collection now 

 preserved at the National Museum. Subsequently, however, he 

 was informed by Dr. Horn that the second typical specimen of 

 M. splendens in the Le Conte cabinet was specifically different 

 from the Floridian species, and that the latter had to be referred 

 to M. Jloridensis. Mr. Schwarz added that upon examination 

 of many specimens of this Mordellistena he found that there was 

 considerable variation in the number and extent of the ridges on
