COCCINELLIDjE. 383 



Scymnus minimus, WolL, Cat. Mad. Col 138 (1857). 

 , Id., Cat. Can. Col. 429 (1864). 



Habitat Maderenses (Mad.} et Canarienses (in Palma sola hand 

 detectus), in inferioribus intermediisque late diffusus. 



This small European Scymnus is widely spread over these Atlantic 

 islands, where very probably it will be found to be universal. It 

 occurs on the foliage of various plants, at low and intermediate ele- 

 vations, particularly in cultivated grounds. It is rather common in 

 Madeira proper ; and it has been captured sparingly in all the Cana- 

 rian islands except Palma, where however we may be pretty sure 

 that it exists. 



1054. Scymnns limnichoides. 



Scymnus Limnichoides, WolL, Ins. Mad. 470, tab. x. f. 3 (1854). 

 , Id., Cat. Mad. Col 139 (1857). 



Habitat Maderenses ( Mad., P* S to ), in intermediis rarissimus. 



A curious little ovate, apterous /Scymnus, which might almost be 

 made to form the type of an allied genus. It seems to be peculiar 

 to the Madeiran Group, and extremely rare. I have taken it 

 sparingly in the sylvan districts of Madeira proper, and more abun- 

 dantly from beneath stones in Porto Santo on an open, grassy 

 mountain-ridge between the Pico do Facho and the Pico do Castello. 



Genus 320. RHIZOBIUS.

Habitat Maderenses (Mad., P* S to , Des.) et Canarienses (ins. omnes), 

 sub lapidibus necnon in graminosis vulgaris. 



There is scarcely any Coleopterous insect which is so widely, and 

 so generally, spread over these Atlantic Groups as the common Euro- 

 pean R. litura. At the Madeiras it is doubtless universal, the 

 northern and southern Desertas being the only islands of the five in 

 which it does not happen to have been detected ; and it has been 

 found in the whole seven of the Canarian archipelago. Its detection 

 in Gomera is due to the recent researches of the Messrs. Crotch. It 

 is recorded by M. Morelet in the Azores.
