56 r August, 



I. Antennse 11-jointed, terminated by a 3-jointed club ; tarsi isomerous, similar in 



the two sexes, in the British families pentaraerous. 

 i. Labrum free, more or less visible. 



A. Maxillae with two lobes : antennse with a feeble elongate club.. 



Beachypteeina.1 



B. Maxillse with one lobe; antennse with a strong, round, compact club 



a. Thorax fitting closely to elytra, not covering base of elytaa 

 ©(•. Abdomen with two segments exposed .... Caepophilina. 

 8. Abdom^i covered, or only apex of pygidium exposed .. 



NiTIDULINA. 



h. Thorax covering the base of the elytra Cycheamina, 



ii. Labrum connate with the front, suture moi'e or less distinct Ipina. 



II, Antennse 11-jointed, club 2-jointed, the 11th joint wholly or partially enclosed 



within the 10th ; tarsi dissimilar in the sexes, heteromerous in the males, pen- 

 tamerous in the females Rhizophagina. 



BEACHYPTEEINA. 



The members of this tribe may be distinguished by their elongate 

 club, bilobed maxillse, and very short, feeble, antennal grooves, which 

 are not visible below the eyes ; it contains two genera. 



1. Claws plainly toothed at base ; extra anal segment of male plain.. Beachypteeus. 



2. Claws not, or hardly, visibly toothed ; extra anal segment of male obscure .. 



Ceecus. 

 Beachypteeus, Kugelann. 



1. Elytra one-third longer than thorax. 



B. gravidus, 111. — Easily distinguished from the other species of the genus by 

 its larger size and more convex form, and by having the elytra much shorter in com- 

 parison to the thorax: the thorax is bisinuate at base, with. the posterior angles' 

 almost right angles. Length, 1^ to 1| lin. 



Not uncommon, but local ; found on the common toad-flax,is 

 Linaria vulgaris ; Hunstanton, Burwell Fen, Maidstone, Mickleham,ii 

 Eeigate, Folkestone, Shiere, &c. 



2. Elytra nearly twice as long as thorax. 



B. puhescens, Er. — Leaden-black, with whitish pubescence ; legs and antenna&l' 



pitchy ; elytra rather lees strongly punctured than is the case with the next species. 



Length, 1 lin. 

 Very common on nettles throughout the country. 



B. urticcB, Kug. — Reddish-brown, shiny ; legs and antennse rufous ; pubescence 

 very thin ; elytra rather longer in proportion to thorax than in the preceding species. 

 and with rather stronger punctuation. Length, 1 lin. 



Yery common on nettles throughout the country. 



These species are very often mistaken for Ileligetlies by beginners, 

 but, apart from other differences, they may at once be distinguished 

 by their partially uncovered abdomen, simple anterior tibise, and. 

 especially in the case of the last two species, by their longer and mud 

 less retractile legs. «
