Grouj) 14. — The form of the head is here again as in 

 Groups 11 and 13; but these two insects cannot be very well 

 arranged with the first of these groups, because the hinder 

 parts of the sides of the mesosternal cavity are less elevated 

 and horizontal ; while from Group 13 they differ by the cavity 

 being less depressed in its posterior part and approaching 

 closely to the suture : from both groups these two species 

 moreover differ in the fact that the hind coxal lamina is of 

 nearly one length throughout, the trochanteral portion being 

 not at all elongate. 



45. Amychus Candezei, Pascoe. 



A. latus, obsciirus, omnino opacus, nigro-fuscus, submarmoratus, 

 parcius breviterque setosulus ; antennis brevibus, rufescentibus, 

 articulis secundo et tertio quam sequentes longioribus, 4-10. sub- 

 sequalibus baud longioribus quam latioribus ; prothorace magno, 

 elytris latiore, angulis posterioribus elongatis, crassis, nullo modo 

 divergentibus, ecarinatis ; elytris latiusculis sed apicibus atte- 

 nuatis, et ibidem parce subseriatim punctatis. Long. 15 m. m., 

 lat. 5| m. m. 



Chatham Islands. I have seen but a single individual, 

 which was kindly given me by Mr. Wakefield. 



Group 15. — The structure of the head in Amychus Candezei 

 is that of the Corymbites forms, as described in Groups 11,13, 

 and 14. The prosternal sutures are not open, but the flanks 

 as it were overlap the central piece. The prosternal process 

 is broad, and is abruptly bent upwards (?) immediately behind 

 the coxae, so that it appears at first to be absent. The meso- 

 sternal cavity is very broad, quite rounded, and very deep 

 posteriorly ; and its borders are nearly horizontal and approach 

 closely to the very deep intercoxal suture. The coxal lamina 

 is very short ; but its femoral portion is distinct throughout, 

 and there is also a distinctly differentiated trochanteral lobe, 

 thouo"h it is both short and narrow. The tarsi are stout and 

 rather short, all the five joints well developed and simple, the 

 4th being only a little smaller than the 3rd. I think the 

 species should be placed very near Corymbites] but as I fancy 

 the prosternal process may have been deformed in the only 

 individual I have examined, I do not feel very clear as to its 

 characters.
