as I have given the full details ofStagetus in my Paper on the "Ano- 

 hiadce of the Canary Islands," this point may perhaps be decided 

 positively by those who possess the genus Tlieca in sufficient abun- 

 dance to permit them to destroy a specimen for dissection. Even 

 should they prove, however, to be identical, I believe that Stagetus 

 will have the priority as regards the date of publication. 



391. Stagetus crenatus. 



Stagetus crenatus, JVoU., Ann. Nat. Hist. (3rd series) vii. 13 (1861). 

 Habitat Teneriffam, rarissimus, inter lichenes ad truncos arborum 

 vetustos crescentcs prgecipue degens. 



Apparently of the greatest rarity, but scattered over the inter- 

 mediate elevations of Teneriffe, — occurring usually amongst lichens on 

 the trunks and branches of trees. In such situations I have taken 

 it in the woods above Taganana, in a smaU Barranco near Souzal, 

 and at Ycod de los Vinhos ; and I have examined a single specimen 

 which was captured by Dr. Crotch — I believe, at Ycod el Alto. 



392. Stagetus hirtulus. 



Stagetus hirtulus, WoU., Ann. Nat. Hist. (3rd series) vii. 12 (1861). 

 Habitat in Gomera et Hierro, in locis simUibus ac praecedens raris- 

 simus. 



Whether the S. Iiirtulus be more than an insular modification of the 

 last species I will not undertake to pronounce for certain. It differs 

 from it mainly in the striae of its elytra being finer and scarcely per- 

 ceptibly (if indeed at all) crenated, and by the pubescence which 

 clothes its entire upper surface being longer and somewhat denser. 

 I have observed it hitherto only in Hierro — where, during Febniary 

 1858, 1 captured it, veiy sparingly, from amongst rubbish at the base 

 of an old waU in an exposed situation near Valverde. Possibly, how- 

 ever, it may have fallen from off the minute Cryptogamic plants with 

 which the waU was partially studded. And I likewise took it in the 

 sylvan district of El Golfo, on the western side of that island. I 

 have inspected an example which was found by Dr. Crotch, during 

 the spring of 1862, in Gomera ; and likewise two others (captured 

 in the same locality) which differ in being larger and in having their 

 elytral striae still more lightly impressed. But I doubt if they can 

 be regarded as more than a " var. /3 " of the hirtulus. 



Genus 164. XYLETINUS.
