being as in that genus though shorter, the joints beyond the fourth 

 not being abbreviated ; it differs from Tetrops also in the irregularly, 

 longitudinally bisulcate and very differently biconstricted prothorax, 

 at least as shown in my series of Ph<za vitticollis Bates. 



NOTES. 



Mem. Col., Ill, pp. 344-345 Tylosis bifasciata Csy., should be 

 advanced to specific rank and conjuncta and parva Csy., united 

 therewith as slight modifications, scarcely worthy of separate 

 names. All the other species described seem to be valid. 



Mem. Col., Ill, p. 355 On page 384 of his recent catalogue, M. 

 Aurivillius has placed Cyllene chara Say, as a modification of decora 

 Oliv. ; this is decidedly wrong; it is not a variety but an amply valid 

 species. The author has nevertheless given names to the variations 

 of chara indicated by G. H. Horn; of these horni Auriv. is typical 

 chara, which was misidentified by Horn on the plate referred to, as 

 can be seen readily by consulting Say's original description, where 

 it is stated that the elytra are solidly yellow in basal third. The 

 mediana of Aurivillius is the same as solida Csy., and of course takes 

 precedence of the latter name because of priority. Arhopalus 

 lutosus Lee., cannot be any modification of chara or decora, though 

 it is unknown to me at present. As for brevipennis Lee., I am 

 inclined to think that the remarkable protrusion of the abdomen in 

 the type is accidental, and that the name may refer to an extremely 

 immature male of Xylotrechus obliteratus. 



Mem. Col., Ill, p. 365 I have recently received from Prof. 

 Cockerell the male of Xylotrechus obliteratus; the elytra have the 

 markings partially obliterated by a uniform suffused clothing of 

 pale hairs, as in the males of insignis and incongruens. Diruptus 

 Csy., should be united with insignis; the differences appear too 

 slight to warrant even the status of a subspecies. A male of Xylo- 

 trechus salebrosus, also recently received, is shorter and with much 

 more rapidly cuneiform elytra and shorter legs than the male of 

 cylindrus, and proves that the two species are distinct. 



Mem. Col., Ill, p. 374 The name Paraclytus is preoccupied by 

 Bates and may be replaced by Triodoclytus (nom. nov.). 



Mem. Col., IV, p. 327 The example from the Catskill Mts., re- 

 ferred to cryptica, does not belong to that species but to variolata.
