252 MEMOIRS ON THE COLEOPTERA 



Atheta (Hilara) sejuncta Csy. (1. c., p. 64) may be considered a syno- 

 nym of Atheta (Hilara) libens Csy. (1. c., p. 63). 



It is probable that Rovalida Csy. (1. c., p. 69) is a synonym of Halo- 

 brecthina Bernh. (Deut. Ent. Zeits., 1909, p. 519). The infra-lateral 

 carinae of the head are very feeble and incomplete and may very easily 

 have been overlooked by Dr. Bernhauer. 



Dimetrota (Dalotia) crucialis (Mem. Col., I, p. 107) is found by ob- 

 servation under better conditions to be a synonym of pectorina Csy. 

 (1. c., p. 106). 



Sableta (Canastota) beatula Csy. (1. c., p. 109) is a synonym of Silusida 

 nanella Csy. (Tr. Acad. Sci. St. Louis, XVI, p. 271) ; the generic reference 

 of the former and not the latter being correct. 



Datomicra insolida Csy. (Mem. Col., I, p. 125) is a synonym of Dime- 

 trota sectator Csy. (1. c., p. 102), the former generic reference probably 

 being more nearly correct than the latter; the species properly belongs 

 to neither genus in all probability. 



Dolosota Csy. (1. c., p. 136) is a synonym of Pancota Csy. (Tr. 

 Acad. St. Louis, XVI, p. 345), the systematic position of the former 

 being correct as a member of the Myrmedoniini. 



Microlia pernix Csy. (Pancota and not Dolosota), Mem. Col., I, 

 p. 144 is, without much doubt, the same as Homalota silacea Erichs. 

 The very peculiar coloration of the antennae seems to indicate this. 



It is highly probable that Hoplandria acudentata Dury (Journ. Cin. 

 Soc. Nat. Hist., XXI, p. 65), the publication date on the cover ap- 

 pearing as September, 1910, but not distributed, according to notification 

 from the Secretary, Mr. Chas. Dury, until Oct. 1st, is the same as 

 Hoplandria Icwiventris Csy. (Mem. Col., I, p. 176), the distribution of 

 the latter work having begun on Sept. 23d and received by a number of 

 institutions on Sept. 24th, 1910. My copy of the Cincinnati publication 

 was not received until Oct. 10, 1910. The latter name therefore has 

 priority by about a week. I greatly regret that there should have been 

 any conflict, and if I had suspected that the species Iceviventris, described 

 from four females, were the same as acudentata, described from the male, 

 I would have withheld the former very properly as being founded upon 

 the female only. Of course there is a chance that my surmise as to the 

 specific identity of the two forms may not be correct, but the evidence 

 upon careful comparison of the descriptions seems to indicate its strong 

 probability. The male in this genus is often materially larger than the 

 female. 



Gnypeta oregona Csy. (Tr. Acad. St. Louis, XVI, p. 199) is a syno- 

 nym of Gnypeta helence Csy. (1. c., p. 193). 



Lissagria impressifrons Csy. (1. c., p. 254) may be regarded as a 

 malformation of Lissagria robusta Csy. (1. c.). Lissagria Iceviuscula 

 Lee., is now represented in my cabinet by a good series; it is the largest 

 species of the genus and the measurements given by LeConte are not far 

 from correct. 



Oligurota Csy. (Ann. N. Y. Acad., VII, 1894, p. 361) must be united 

 with Thecturota Csy. (1. c., p. 357) as no better, at the best, than a sub- 

 genus.
