tera the same part is subtruncate ; the emargination in T. asqualis is less than 

 in the other two, but is quite obvious. This genus may be separated under the 

 name E u g a s tr a. 



14. Polyphylla variolosa Harris, is referred by Erichson (Ins. Deutschl. 

 659) to Melolontha occidentalis Linn., an entirely different species of the 

 same genus, which is found in the Southern States, and which has the suture 

 a nd three vittae on each elytron covered with white hair. 



15. Melolontha 10-1 in ea ta Say, a species of the same genus, is closely al- 

 lied if not the same as the Mexican Polyph. leucogramma Blanch. (Cat. Mus.161.) 



16. Atractopterus incongruus Lee. (Trans. Am. Phil. Soc. JO, 454) is 

 very similar to the European Sericosomus fugax ; the name Sericosomus is 

 founded upon characters, although recognizable, too slight to be admissible in a 

 system of rational classification, but as its type coincides with Atractopterus, it 

 seems proper that the latter name should be suppressed. 



17. Pyractomena linearis Lee. Proc. Acad. 5, 336, is P. lucifera Mels. 

 ibid. 2, 304 ; the latter name I placed incorrectly as a synonym of P. angulata. 



18. Pyractomena fenestralis Mels. ibid. 2, 304, is not Ellychnia c o r- 

 r u s c a, as stated by me (Proc. Acad. 5, 334) but another species of Ellychnia, 

 allied to E. ni grica n s. 



19- Alloeocnemis Lee. Proc. Acad, 6, 232. This must be added to the al- 

 ready numerous synonyms of Polycaon Lap. which has been passed from 

 Cleridae to Melyridae, and as in the present instance to Nitidulidae. Its true 

 resting place is, as indicated by Erichson in Ptiniores, where it approaches on 

 the one hand Apate, and on the other Lyctus ; a curious species found in Texas 

 by Lieut, Haldeman completes the chain of analogy in form and sculpture. 



20. Triphyllus r u g o s u s Randall, (Cis rugosus Mels. Cat. Descr. Col. 85,) 

 is Endecatomus reticulatus Mellie, Ann. Ent. Soc. Fr. 2d, 6, 213. 



21. Xyletinus sericeus Say, Journ. Acad. 5, 171, belongs to Trypopitys 

 Redt. 



22. Xyletinus flabellicornis Sturm, Cat. (1826) tab. 1 , fig. 7, does not 

 belong to the family of Ptiniores, nor can I at present indicate where it should 

 be placed. 



23. Tomicus 1 i m i n a r i s Harris, (Ins. Inj. Veget. 78,) found by Miss Mor- 

 ris to inflict serious injury upon peach trees, belongs to Phloeotribus. 



24. Pachyvhynchus Schonherri Kirby, Fauna Bor. Am. 203; Rhinaria 

 Schonherri Schonh. 7, 2,369, is merely Ithycerus curculionoides Schonh. 1,246. 



25. Brachytarsus obsol.etus Schonh. (1839) 5, 167, is Anthribus variegatus 

 Say, (1826) Journ. Acad. 5," 251. 



26. Brachytarsus brevis Schonh. (ibid.) is Anthribus tomentosus Say, ibid. 



27. Anthribus coronatus Schonh. (1833) 1, 141, is A. cornutus Say, (1831.) 

 Curcul. 4.- 



28. Anthribus capillicornis Say, (1826,) is Arascerus coffeaB Schonh. (Fabr.) 



29. Anthribus 4-notatus Say, (1826,) is A. bimaculatus Oliv. and belongs to 

 Tropideres. 



30. Trichocnemis Lee. (Journ. Acad. 2d, 2, 110) is not sufficiently distinct 

 from Ergates ; the Californian species must therefore be called E.spiculatus. 



32. Tinopus Lee. (ibid. 2d, 2, 19) is the same as Rhopalophora Serv. 



33. The genus Argaleus Lee. (ibid. 2d, 1, 319) is founded on defective cha- 

 racters ; the type A. nitens is congeneric with Leptura monticola Randall, 

 upon which I founded Evodinus ; the latter genus must therefore be suppressed.
