ELATERID7E. 



539. Throscus integer. 



Trixagus integer, Woll, Cat. Mad. Col. 82 (1857). 

 Throscus integer, Id., Append, huj. op. 31. 



Habitat Maderenses (Mad.), rarissimus ; hinc inde in lauretis humi- 

 dis excelsis. 



Found in the damp sylvan districts of a rather high elevation in 

 Madeira proper, where however it is extremely scarce. I have taken 

 it beneath rotten wood, at the Montado dos Pecegueiros, in the north 

 of the island. 



II. Oculi in media transversim sulcati. 



540. Throscus 



Throscus elateroides? Heer, Fna Helv. 443 (1841). 

 Trixagus gracilis, Woll, Ins. Mad. 237 (1854). 

 , Id., Cat. Mad. Col. 84 (1857). 



Habitat Maderenses (Mad.), sub cortice laxo necnon inter liehenes 

 ad lignum antiquum crescentes in inferioribus rarissimus. 



The few examples which I have yet seen of this Throscus were 

 taken by myself at a low elevation in the south of Madeira proper 

 namely under the loosened bark of a plane-tree in the Praga da 

 Rainha in Funchal, and amongst lichen growing on the rotten wood 

 of an old peach-tree in the Rev. R. T. Lowe's garden at the Levada. 

 In all probability the species will be found to be identical with the 

 T. elateroides of southern Europe ; but until further material has 

 been obtained for comparison, I will not suppress the name under 

 which it has hitherto been cited, particularly as De Bonvouloir 

 (judging solely, however, from my diagnosis) records a doubt as to 

 whether it is absolutely conspecific with that insect. Should it ulti- 

 mately prove to be so, of course Heer's title would have the priority.
