HALTICIDJE. 



Genus 311. PSYLLIODES. 

 Latreille, Fam. Nat. des Ins. 405 [script. Psylliode] (1825). 



1020. Psylliodes chrysocephala. 



Chrysomela chrysocephala, Scop, fnec Linn., sec. Mus.\ Ent. Cam. 



213 (1763). 

 Psylliodes chrysocephala, Woll., Ins. Mad. 449 (1854). 



, Id., Cat. Mad. Col. 134 (1857). 



, All., Ann. de la Soc. Ent. de France, 810 (1860). 



Habitat Maderenses (Mad.), hinc inde in intermediis praecipue cultis. 



This common European Psylliodes occurs sparingly in the inter- 

 mediate districts of Madeira proper, particularly in cultivated spots-; 

 but it has not yet been observed in the Canaries. Yery probably it 

 may have been established at Madeira from more northern latitudes. 



1021. Psylliodes umbratilis. 



Psylliodes umbratilis, Woll., Ins. Mad. 450 (1854). 



, Id., Cat. Mad. Col. 134 (1857). 



, All, Ann. de la Soc. Ent. de France, 339 (1861). 



Habitat Maderenses (Mad), in editioribus rarissima. 



The very few specimens which I have yet seen of this Psylliodes 

 were captured by myself in the higher elevations of Madeira proper, 

 where it would appear to be extremely rare. Possibly it may prove 

 to be but a geographical state of the common European P. napi ; 

 but until further, and more satisfactory, material has been obtained, 

 it is difficult to arrive at any positive conclusion on this point*. 



1022. Psylliodes amplicollis. 



Psylliodes amplicollis, Woll., Append, huj. op. 56. 

 Habitat Maderenses (Mad.), a Dom. Bewicke semel deprehensa. 



The only example of this species which has hitherto come beneath 

 my notice was captured in Madeira proper by the late Mr. Bewicke, 

 in whose collection alone it consequently exists. In some respects 

 it is intermediate between the umbratilis and vehemens, and, al- 

 though I do not believe that it can be any modification of either of 

 them, I feel that further material is necessary before the species is 

 satisfactorily established. 



* Mr. Rye, to whom I communicated an example of the P. umbratilis, remarked 

 as follows: " Closely allied to our napi, from which, however, it seems to differ 

 somewhat chiefly in the very evident punctation of its interstices, but likewise 

 in the more feeble build of its legs, smaller size, slightly different colour, and 

 more sloped shoulders."
