In the present short essay I propose to give the results of my syno- 

 nymical study, or at least my present determinations, as a closer study 

 when the descriptions are to be written may possibly modify the views 

 here given. 



In a paper published by me (Trans. Am. Ent. Soc. '78, p. 137-138) 

 I have shown that Tostegoptera, Eugastra, Endrosa and Gynnis should 

 be united with Lachnosterna. This view I have seen no reason for 

 changing. 



Among the species at present in our lists there is some confusion and 

 more synonymy. In order to make the synonymy clear I propose to take 

 the authors by date of seniority. 



Froehlich describes fusca and crenulata. 

 Fabricius describes trislis. 



Knoch describes quercus, micans, ilia's, hirticula, hirsuta, pilosiollis 

 (— tristis) quercina (=fusca). 



Gyllenhal describes fervens (=fusca) K?wchii and georgicana (=cren- 

 ulata). 



Say describes longdarsis, ephilida, balia and lanceolata. 

 Harris describes fraterna ; Hentz describes porana (=ilicis). 

 Melsheimer describes rugosa and pruinosa II (=prunina Lee). 

 Blanchard (Ent. Mus. Paris) described many species from our fauna 

 and quotes a number of others some erroneously. As many of those 

 species were unknown to Dr. LeConte, it has been thought advisable to 

 condense what is known of them. They are all described as Ancylonycha. 

 L. profunda Bl. distinct species allied to rugosa and Knochii. 

 brevicollis Bl. a race of fusca. 

 ftrvida \ Bl. is crassissima Bl. 



puncticollis Ml. probably a good species allied to fusca. 

 fervens \ Bl. is congrua Lee. 

 unifurmis Bl. is ephilida Say. 

 pruinosa % Bl. is gibbosa Burm. {futilis Lee.) 

 crenulata \ Bl. is hirticula, 



crassissima Bl. subsequently described as obesa Lee. 

 longicornis Bl. I have examined the type but it is doubtful as 

 a member of our fauna, all the other species given by Castel- 

 nau are from Brazil. 

 „ micam % Bl. is prununculina [cerasina Lee.) 

 „ diffinis Bl. is allied to fraterna, has a very long antennal club 

 and the last ventral ^ not impressed. It is from South Caro- 

 lina, M. Salle informs me, not Texas. 

 Burmeister (Handbuch [855) follows with a much greater series.de- 

 scribed as Ancylonycha and Trichestes.
