CRYPTOPHAGID^E. 145 



413. Atomaria insecta. 



Atomaria insecta, WolL, Cat. Mad. Col. 61 (1857). 



Habitat Maderenses (Mad.), sub foliis marcidis in sylvaticis humidis 

 editioribus rarissima. 



A Madeiran Atomaria belonging, like the following one, to an 

 indigenous and rather peculiar type. It has been found only in 

 Madeira proper, where it occurs (though very rarely) beneath damp 

 leaves and refuse in the sylvan districts of a high elevation. The 

 Lombarda das Yacas is the principal region in which I have ob- 

 served it, on the mountains to the east of Sao Vicente, in the north of 

 the island. 



414. Atomaria alternans. 



Ephistemus alternans, JVolL, Ins. Mad. 177 (1854). 

 Atomaria alternans, Id., Cat. Mad. Col. 62 (1857). 



Habitat Maderenses (Mad.), in locis similibus ac prsecedens sed 

 frequentior. 



Likewise peculiar to the sylvan regions of Madeira proper, where 

 it occurs in the same kind of places as the A. insecta, but (although 

 decidedly scarce) somewhat more frequently. 



Genus 127. EPISTEMUS.

415. Epistemus gyrinoides. 



Dermestes gyrinoides, Mshm., Ent. Srit. 77 (1802). 



Phalacrus dimidiatus, Sturm, Deutsch. Fna, ii. 85, t. 32. f. i> (1807). 



Ephistemus gyrinoides, Steph., Ill Srit. Ent. ii. 168 (1829). 



- dimidiatus, Woll, Ins. Mad. 176 (1854). 



- gyrinoides, Id., Cat. Mad. Col. 63 (1857). 

 Epistemus gyrinoides, Id., Cat. Can. Col. 144 (1864). 



Habitat Maderenses (Mad.) et Canarienses (Can., Ten., Gom.), sub 

 quisquiliis haud infrequens. 



The E. gyrinoides, so universal throughout Europe, is widely 

 spread over these islands ; and though nowhere very abundant, never- 

 theless, when searched for in the proper localities, it will probably 

 be found to be nearly universal in both Groups. Hitherto it has 

 been detected only in Madeira proper ; and in Grand Canary, Tene- 

 riife, and Gomera, of the Canarian archipelago.
