1367. Philontlms filiformis. 



Philonthus filiformis, WolL, Ins. Mad. 585 (1854). 

 , Id., Cat. Mad. Col 192 (1857). 



Habitat Maderenses (Mad.'), in humidis intermediis rarissinms. 



Apparently the Madeiran representative of the last species, t 

 which it is very closely allied though the several constant cha- 

 racters which separate it therefrom have been pointed out in my 

 Canarian Catalogue. In reality it is perhaps still more akin to the 

 European P. procerulus, of which indeed it is possible that it may be 

 but a geographical state. Hitherto I have observed it only in damp 

 spots of intermediate altitudes in Madeira proper, where moreover it 

 would seem to be extremely rare. 



1368. Philonthus xantholinoides. 

 Philonthus xantholinoides, Wott., Cat. Can. Col. 577 (1864). 



Habitat Canarienses (Ten.}, inter lapillos ad marginem paludis cujus- 

 dam juxta urbem Sanctse Crucis semel lectus. 



A single example of this distinct little Canarian Philonthus was 

 taken by myself amongst wet shingle, in the Barranco Santo, near 

 gta c ruZj i n Teneriffe ; but it is all that I have yet seen. 



(Subfam. V. XANTHOLINIDES.) 



Genus 403. XANTHOLINUS. 

 Dahl, in Encyclop. Method, x. 475 (1825). 



1369. Xantholinus marginalis. 



Xantholinus marginalis, Woll., Trans. Ent. Soc. Land. i. 187(1862). 

 , Id., Cat. Can. Col. 578 (1864). 



Habitat Canarienses (Lanz., Fuert., Gom.), rarissimus ; in Euphorbiis 

 emortuis putridis degens. 



Attached to the rotting Euphorbia-stems, in the Canarian Group, 

 where it would appear to be rare. It was captured by Mr. Gray 

 and myself in the north of Lanzarote, by myself in the little islet of 

 Lobos (off the north of Euerteventura), and a single specimen was 

 taken by Dr. Crotch (out of a Euphorbia canariensis) in Gomera. 

 Although smaller than that insect, with its head and prothoracic 

 series much more densely punctured, and with the margin of its 

 pronotum diluted in hue (particularly behind), this fine Xantholinus 

 (in its brightly rufo- testaceous elytra) has much the general colour- 

 ing of the European X. glabratus.
