78 COLEOPTERA. 



by himself in June, in felled fir-trunks, under the bark, 

 emerging from cylindrical burrows, that almost reached the 

 centre of the tree. As Mulsant states *^ Quelquefois elle 

 eclot dans les villes, au sein des arbres (sapins) qui y sont 

 transportes," it seems not at all improbable that, if any part 

 of the warehouse in which the Leicester insect was found 

 were built of Norway pine, the mystoy of its appearance is 

 readily capable of explanation. 



Serroiialpus is closely allied to PliJoeotrya and Zilora, 

 and is distinguished by its maxillary palpi being very large, 

 w^ith their 2nd joint triangular, the 3rd very short and inter- 

 nally hamate, and the apical very large and lunate. Its 

 antennse are filiform, and as long as half the body in the $ . 

 The sole known species of the genus, as now restricted, is 

 very variable in size, but apparently always larger than ordi- 

 nary specimens oi Phloeotrya rufipes; it is elongate, linear, 

 convex, narrow behind, opaque, very finely rugose-punctate, 

 and brown in colour, with silky pubescence. Its elytra are 

 obsoletely striated, and its thorax has the postero -lateral 

 margins sharp and compressed, and the hinder angles acumi- 

 nate. 



BarhatuSj Schaller, is given as a synonym of striatus by 

 De Marseul, Redtenbacher refers that name only to Fabri- 

 cius and Duftschmidt; but if Schaller be the real author of 

 it, I do not understand why his name is not adopted, as it 

 must have been published in his '*' Neuelnsecten beschrieben," 

 in the Schrift. naturf. Gesellsch. Halle, 1783, i, p. 217 et seq.y 

 three years prior to Kellenius's work.
