78 MAND1BULATA. — COLEQPTEBA. 



ford, and a few in the following spring: — it also occurs beneath the 

 bark of trees, in dunghills, &c. "Ensham, Oxon." — Mr. Weshoood. 



Sp. 11. serratus. Oblongo-ovatus, fusco-Jerrugineus, pubescens, thorace subro- 

 tundo postice scrobiculato, lateribus serrulatis, elytris punctulatis. (Long, 

 corp. 1 lin.) 



Co. serrata. Marsham. — Cr. serratus. Steph. Catal. 86. No. 932. 



Oblong-ovate, fusco-ferruginous, pubescent, deeply punctate; thorax sub- 

 quadrate, with the margins a little rounded and serrated, the disc glossy, 

 black, convex; elytra oblong, slightly convex, a little punctulate: clothed 

 with rather long pubescence ; pitchy-brown, with the apex somewhat paler : 

 body pitchy-black, with the tip paler: antenna? and legs pale rufo-ferru- 

 ginous. 



Some examples are of a paler colour; — probably immature. 



The rounded margins to the thorax, giving that part a rounded appearance, 

 combined with their crenulations and the absence of a denticle towards their 

 middle, at once point out the characters of this species. 



Common throughout the metropolitan district, especially in the 

 autumn and spring. " Not uncommon under bark (near Swansea), 

 and Mr. Jeffreys has found it rather plentiful in the decaying flowers 

 of Ilex europeus in May." — L. W. Dillwyn, Esq. 



Sp. 12. runcornis. Oblongo-ovatus, rufo-piceus, crebre punctatus, subpubescens, 



capite elytrorumque apicibus dilutioribus , antennis nifis. (Long. corp. 1 lin.) 

 Cr. runcornis. Steph. Catal. 86. No. 933. 



Oblong-ovate, deep rufo-piceous, with the head and apex of the elytra pale, the 

 latter especially : the thorax short, subquadrate, with the lateral margins 

 produced into a sharp denticulation at the anterior angle, and a second about 

 the middle, less distinct and somewhat obtuse : the elytra are rather deeply 

 and very distinctly punctate throughout, the punctures disposed in lines, 

 especially near the suture: the head and thorax are both rather coarsely 

 punctate : legs pale ferruginous ; antennae rufous. 



The bright rufous antennae of this species, with the deep colour of the elytra, 

 and the coarsely punctate surface, distinguish this small species from its con- 

 geners. 



Taken within the metropolitan district. 



B. With the lateral margins of the thorax very obsoletely crenulated: the tarsi 

 with the second and third joints bi!obed*. 



* The two insects which belong to this section of Cryptophagus differ in 

 several points from the type of that genus, and will probably hereafter be formed 

 into a genus;— in the structure of the tarsi they closely resemble the insects of 

 the following genus, with which Latreille unites one of the species, but in other 

 points they disagree.
