100 BRITISH BEETLES. 



elytra, and the three basal joints of all the tarsi widened. 

 We possess one genus only, Cychramus ; the species of 

 which, brown, broad, and very pubescent, abound in 

 May-blossom and fungi. 



The PHALACRIDES (by many authors entirely removed 

 from the Nitidulidae) differ from the other sub-families 

 in having their coxae approximated ; the anterior being 

 globose instead of nearly oval and transverse, and the 

 posterior transverse, semicylindric, and close together, 

 instead of being separated by an elongation of the first 

 ventral segment of the abdomen. Their tarsi, also, have 

 the three basal joints velvety beneath; their palpi are 

 filiform, instead of short; they have two lobes to the 

 maxillae (as in the Br achy pter ides) ; and the elytra are 

 convex, covering the whole of the abdomen. Our species 

 are all small, shining, and found chiefly on flowers. 



The IPIDES have a single lobe to the maxillae; the 

 front of the head produced so as to cover the labrum ; 

 and the fourth joint of the tarsi very small ; the elytra 

 (except in Cryptarcha) not entirely covering the abdo- 

 men; the antennae (except in Rhizophagus) eleven-jointed, 

 and the tarsi five-jointed, except in the male of the last- 

 named genus, of which the posterior tarsi have only four 

 joints. 



Cryptarcha (which very much resembles certain of 

 the Nitidulides, and is found at the sap of trees, espe- 

 cially if Cossws-infected) has its mesosternum covered 

 by an elongation of the prosternum ; which elongation is 

 not so evident in other genera. Ips, flat, elongate, 

 shining, and mostly black with red spots, frequents 

 freshly- cut pine-trees, etc., beneath the bark of which 

 its larvae are found. M. Ferris (' Annales/ ser. 3, i. 

 p. 598 et seq.) states that /. ferrugineus enters into the
