Phloeophthorus rhododactylus, Brit. Cat. Vol. v. p. 423. 

 Just after the last sheets of the Scolytidce had gone to press I received 

 the following communication from Mr. W. F. Blandford, and am glad 

 to have the opportunity of inserting it: 



" I find that in the two European species of Phloeophthorus, "Woll., 

 namely P. rhododactylus, Marsh., and P. spartii, Nord., there has been 

 confusion of nomenclature. The insect called abroad P. spartii is our 

 v. Marsham's P. rhododactylus (its proper and prior name) ; while the 

 P. rhododactylus of the Continent is unknown here and does not really 

 possess any separate name at all. 



" The proper synonymy will be as follows : 



" Phloeophthorus rhododactylus. Ips rhododactylus, Marsham, Ent. 

 Brit. Col. p. 58. 



" H. rhododactylus, Gyll. Ins. Suec. iv. 619 nee. Eatzeb; Chapuis; 

 Eichhoff. 



tl Phloeophthorus perfoliatus, Woll. Ins. Mader. p. 301. PI. 6, Fig. 1. 



"Hylesinus spartii, ]ST6rd. Stett. Ent. Zeit. 1848, p. 250. 



" Hylesinus tarsalis, Foerst. Verhandl. Nat. Ver. Kheinl. 1849, 383. 



" Phloeophthorus spartii, Chapuis, Eichhoff, etc. 



" Phloeophthorus Chapuisii, mihi. 



" H. rhododactylus, Ratz., Forstius. I. p. 178. PI. 7, Fig. 13. 



"P. rhododactylits, Chapuis, Synopsis, p. 43. 2. v. Thomson, v. Eich- 

 hoff, v. Lowendal. 



" I hope to publish a note of this in ona of the foreign papers. If 

 you have time to get in the synonymy at all into your book it would be 

 convenient. 



"I may add that I have seen the original specimens in Kirby's collec- 

 tion from which Marsham described his." 



It is evident that a considerable amount of work yet remains to be 

 done among the Scolytidae, and we may hope that Mr. Blandford will be 

 enabled to clear up many more doubtful points regarding them. 



In the Biologia Ceutrali-Americana, Coleopt. Vol. iv. Dr. Sharp is 

 doing work on the Khynchophora of Central America which will help 

 to clear up several unsatisfactory points in our present classification of 

 the group: I have only had the opportunity of seeing a small portion of 

 this work (Pt. 3, March 1891, pp. 81, et seqq.) ; the following remarks 

 regarding the sub-fam. Otiorrhynchinas are of general interest : 



" The family is defined in a satisfactory manner by the existence of 

 a scar on each of the mandibles, due to the detachment of a peculiar 

 pair of cutting instruments, supposed to be used by the insect for free- 

 ing itself when emerging from the pupal stage (vide Vol. V. p. 170). I 

 propose to divide the family into two divisions, consisting (I.) of the 

 apterous, (II.) of the winged Otiorrhynchinse.
