(FauveJ), Gibraltar, Civita Yecchia, and Salonica (J. J. Walker), . 

 Morea (Beiifer), &c. The British specimens hitherto referred to it 

 belong to one or the other of the following species. 



P. Hafzehurgi, Wissm. — This is the insect commonly found in 

 granaries, bakehouses, &c., and often met with in bread or flour, 

 Wissman found it under the bark of a dead beech at Miinden, 

 Hanover, and it has also been found by others under bark. It is the 

 P. depressus of Stephens, all the specimens in his collection belonging 

 to it. I possess examples from London, Scarborough (Zaw;so?z), Ripon 

 {E. A. Waferhouse) , &c., as well as from many European localities, 

 Tunis, and Asia Minor. The uniseriate punctuation of the elytral 

 interstices seems to be a constant character of this species. The P. 

 (Hi/pophleeus) depressus and P. floricola of Marseul, from Japan,*- 

 belong here. The original specimen of P. amhiguus, Woll., was found 

 in the upland region of Madeira, whither, as Wollaston believed, it 

 appears to have been carried (with Sifophilus oryzce) in provisions. I 

 am indebted to Herr E. Keitter for the loan of two specimens of P. 

 Batzehirgi, determined by Dr. Seidlitz. 



P. subdepressus, Woll. — Also found in granaries. Apparently less 

 common than the preceding, and easily separable from it by the more 

 dilated, posteriorly prolonged antennary orbits, which are limited 

 inwards by a deep oblique groove, and the fine punctuation of the 

 surface. t In many of the largest and broadest examples ( ? ), 

 received with others from the same localities, there is an irregular 

 double row of minute punctures on the two or three inner elytral 

 interstices, instead of a single row on each, as in the type ; they can- 

 not be separated from P. subdepressus. I have seen specimens from 

 London granaries ; also from various localities in the south of 

 Europe (Gibraltar, Turkey), Tangier, Syria {Reitter), Cape Verde Is., 

 Mexico^, Texas, Gilbert Is., &c. M. Fauvel, too, has sent me a 

 number of specimens from Rouen, found in a shipment of ground- 

 nuts (Arachis). Wollaston's original example from the Canary Is. 

 was found under camel's dung. 



The other described species of Palorus are : — 



P. delicatulus, Reitter (1877), from E. India. The type of this 

 species (or rather the remains of it, for the head and prothorax are 

 broken off) is contained in M. Rene Oberthiir's collection. " Smaller

 t These characters are accurately described by Wollaston. 



{ The specimens from northern Mexico refei-red by me (Biol. Centr.-Am., Col. iv, 1, p. 174) 

 to P. meliiian belong here.
