"Among the numerous minor errors may be cited that the 

 type of the genus Neocatolaccus Ashmead is not N. tyloder- 

 iinc Ashmead of the Mem. Carn. Mus. , without description, 

 but Catolaccns Ivlodcrnnc Ashmead, which was described 

 years previously and which in this work is still cited under 

 Catolacais. The genera Encyrtocephaluf , D/noi/ra, Brack v- 

 scelidiphdga, and Diaiilomorpha were all described by Dr. 

 Ashmead in the Proc. Linn. Soc. N. S.W. in 1900,together with 

 their type species, and not in his classification of Chalcidoidea. 

 A perusal of the alphabetical list of genera given by Dr. Ash- 

 mead at the end of his work would have saved Dr. Schmiede- 

 knecht these as well as other errors in citation." 



Mr. Schwarz exhibited living and alcoholic specimens of 

 the large coccid Llaveia axin Llave (Family Monophlebidce). 

 The specimens were found by him last December at Tampico, 

 Mexico, thickly covering the branches and thicker twigs of 

 several different trees (the names of which could not be ob- 

 tained) in a very circumscribed locality during the month of 

 December. All bushes and lower vegetation beneath the in- 

 fested trees were killed by the fungus growing on the saccha- 

 rine exudation of the coccid. Some of the males were seen 

 flying about the trees, but no coccinellid beetles or any other 

 enemies of the coccid could be seen ; nor were the coccids attend- 

 ed by ants. Living specimens kept in a tin box without food 

 are still alive and excrete a much more copious cottony excre- 

 tion than when the species was observed in nature. The paper 

 label in the vial in which the alcoholic specimens were kept 

 has acquired a beautiful pink color. 



-Mr. Caudell said: 



"Thunberg in 1815 erected the genus Conocephalns with sev- 

 eral species under it. One of the originally included species, 

 hemipterusu. sp. , has quoted under it as a synonym the (*r\l- 

 liis ( Tettigonid} conocephalus of Linnaeus. The original 

 inclusion of a species conocephalus in the genus of the same 

 spelling, even though in synonymy, is considered as coming 

 under the rule of type selection by absolute tautonomy, and thus 

 conocephalus Linnaeus, of which the later described hemipterus 

 Thunberg is a synonym, is the type of Conocephahis Thun- 

 berg. This fact has been quite universally conceded for some 

 years and cannot well be ignored. Otherwise I would ear-
