ADDITIONAL NOTES. 



Among the many extraordinary errors made by Dr. Horn 

 in his recent synonymical list (Ent. Amer. I, p. 108), there 

 is perhaps none so remarkable as that relating to a species 

 which was described by me under the name Notoxus delicatus, 

 and which is there stated to be a synonym of N. Pilati Laf. 

 N. monodon Fabr., of which N. Pilati is considered a var- 

 iety, is, as well known, a single-banded species, the band 

 crossing the elytra slightly behind the middle and being 

 produced forward for a short distance along the suture. 

 The principal distinguishing feature of the variety N. Pilati 

 is, according to La Ferte's description, which is before me, 

 the disintegration of this single band into three spots, one 

 sutural and two transversely elongated lateral spots. Again, 

 one of the chief reasons influencing La Ferte" in its separa- 

 tion, is the fact that it is a local form, being only found on 

 the small Island of Galveston, in the Gulf of Mexico and off 

 the coast of Texas. On the other hand N. delicatus is not a 

 single-banded species in any sense, but has two distinct and 

 entire transverse bands, the anterior one being in advance 

 of the position occupied by the single band of monodon, and 

 the second between this and the elytral apices. In other 

 words the style or general character of the maculation is of 

 such an entirely different order, that we cannot imagine any 

 mutation from one to the other; N. delicatus is also much 

 smaller than N. monodon, or its variety Pilcdi. 



Another singular error is that concerning Eumicrus punc- 

 tatus of the Scydniasnidee, which, according to Dr. Horn, is 

 synonymous with Cholerus Zimmermanni Schaum. I have 

 before me the original description of Schaum of his Scydmai- 

 nus Zimmermanni, and quote the following passages with 

 their equivalents from the description of E. punctatus (Cont. 

 II, p. 86) :
