eluding Chiasognathus Grantii (^ and $ ; a new genus of Lucanida: 

 allied to the latter ; a new genus apparently allied to Cebrionidce, 

 but having some relation with Parandra and Sagra, Torneutes (Reich), 

 Cocytia Durvillei, &c. ; also specimens of a minute species of spider 

 found in the neighbourhood of Paris, in which the eyes of the male 

 are placed upon a thick peduncle arising from the front of the cepha- 

 lothorax {Micryphantes galeatus, Kock. Panzer, Suppl. 121, f. 23 ?). 



He also exhibited the following insect monstrosities : Oryctes 

 nasicornis $ , in which the anterior femur of the right side was some- 

 what enlarged, and supported three tibiae and tarsi of the ordinary 

 size, two of the tibiae being soldered together longitudinally, but the 

 tarsi being free. Melolontha vulgaris, in which the anterior leg on 

 the right side is similarly tripartite, but the different portions less 

 developed. (See Ann. Soc. Ent. France, torn. iii. pi. 1. A.) Carabus 

 auratus, in which the right antenna is furcate at the extremity of the 

 fifth joint, the upper portion being 6-jointed and the lower 4-jointed. 

 (See Ann. Soc. Ent. France, he. cit., fig. 2.) Cebrio Gigas ^ , in which 

 the left antenna is very short, with serrated triangular joints, and the 

 posterior tarsus on the left side very thick. 



He also exhibited several species of Dermestidte, and pointed out 

 the existence of ocelli in these insects. He also exhibited an ex- 

 tensive series of drawings intended to illustrate monographs of the 

 genera Scorpio, Gastracanthus (Fam. Epeirida), and new Crustacea, 

 from the Voyage of D'Orbigny, and likewise a manuscript of Cuvier, 

 published in Silbermann's ' Revue Entomologique.' 



The Senator Van Heyden, of Franckfort, exhibited specimens of 

 the following insect monstrosities, namely ; Prionus coriareus $ , hav- 

 ing three legs arising on the right side, at the extremity of the meta- 

 .sternum : of these legs one was of the ordinary size, and corresponded 

 with that on the left side ; the other two were of unequal and smaller 

 size, and apparently abortions, but having the different parts distinct. 

 A Prionus from Paraguay, having two legs arising at the right side 

 from the extremity of the metasternum, one of which was of the 

 ordinary size, and corresponded with the left hind leg, but the other 

 was very short, having the trochanter and coxa distinct, the femur 

 and tibia apparently soldered together into a straight piece, the tarsi of 

 the ordinary form. Calathus fuscus with one of the antennae trifur- 

 cate. Eumolpus nitidus, with the anterior tibia on the right side, 

 very broad and triangular, tripartite beyond the middle, with three 

 perfect tarsi. Carabus emarginatus 9 having the left antenna 9-jointed 

 laterally, and emitting two continuous joints at the extremity of the 

 second joint. Meloe proscarabceus J" with the right jjosterior femur 

 thickened and supporting three tibiae and tarsi. CalalJitis ciste-
