MORE NEW GALERUCINE BEETLES 

 WITH EXCISED MIDDLE TIBIAE IN THE MALE 



By Doris H. Blake 



Honorary Research Associate, Department of Entomology 



This paper is a supplement to "A Review of Some Galerucine 

 Beetles with Excised :Middle Tibiae in the Male" (Proc. U.S. Nat. 

 Mus., vol. 108, 1958) which, owing to its delayed publication, appeared 

 subsequent to a paper by J. Bechyne (Ent. Arb., vol. 7, 1956), wherein 

 he described the genus Trichobrotica, giving the same type of the genus, 

 Neobrotica sexplagiata Jacoby, that I had for my new genus Iceloceras, 

 He described only one new species under this, Trichobrotica brasiliensis, 

 the type of which I have examined. Since it is my Iceloceras flavipes, 

 I am transferring to the genus Trichobrotica those species described 

 by me under Iceloceras although I recognize that some of them do not 

 fit entirely into the rather narrow limits of Bechyne's genus described 

 from two very similar species and having as the only characters 

 coarsely punctate elytra with sparse pubescence and with vertical 

 elytral epipleura visible the entire length. Bechyne did not note the 

 excised middle tibiae in the male, which, together with the lack of 

 any sexual differences in the antennae, I had taken as characters 

 separating Iceloceras from other genera with excised middle tibiae. 

 In general most beetles of the group with excised middle tibiae have 

 unusual antennal development in the male also. In Trichobrotica I
