prominent, and is longituclinall}* convex, and it is sejDarated from the 

 strongly -elevated front point of the raised metasternal area bj a distinct 

 chink : this character and the elytral striation separate the species 

 absolutely from all the following forms. The length with the head 

 extended is usually quite 2| mm., but the species is a "little variable, 

 some specimens being rather smaller, and more pointed behind, and the 

 metasternal chink somewhat- reduced. At present it is unnecessary to 

 distinguish these by a separate name. The male is distinguished by the 

 dilatation of the apices of the lateral lobes from that of C. lugichris. 



The name minutus by which this species was known for several 

 genei^ations has been changed on insufficient grounds by some authorities, 

 but the proposal to do so does not appear to meet with general acceptance, 

 being rejected by Seidlitz, Kuwert, and Rey. 



Though far from abundant C. minutus is widely distributed in 

 England and Scotland. 



2. — Cerycon granarius, Er. 



Readily distinguished from small C. minutus by the more shining 

 elytra, the serial punctuation of which is distinct at the apex. The 

 sj)ecies is very like small C. analis, though the structure of the sterna is 

 very different in the two, and in granarius the diffuse punctuation of 

 the elyti*a is wanting. On the under surface the mesosternal plate is 

 shorter than in G. minutus ; it is oval, rather broad, and pointed behind ; 

 the metasternal anterior point very nearly touches the mesosternal lamella, 

 indeed the two appear to be in contact, but a careful examination shows 

 that there is a distinct gap between them. 



From the following species C. granarius is distinguished by the 

 shining elytra and the more inflated second joint of the palpi, as well as 

 by the broader mesosternal lamella ; the palpi are piceous-yellow. 



I have only one specimen, which Avas given to me by G. R. Crotch 

 at the time the species was first distinguished in this country (Ent. 

 Annual, 1869, p. 38) ; it is a female, and has the elytra vaguely paler 

 on the apex. 



There is no reason to doubt the distinction of granarius from 

 luguhris. C. J. Thomson was the first to point out the difference in 

 the mesosternal lamina of the two (Skand. Col. ix, 18G7, p. 126). 



3. — Cerycon lugubris, Payk. 



Extremely like the smallest specimens of C. minutus, but besides 

 having the <?lytra striate at the tip, the structure of the sterna is quite
