Cis rhododactijlus, Steph. Illustr. iii. 346, 8. 



Ptinus rlwdodactijlu^, Marsh. Ent. Brit. 87, 22. 



Cis nigricurnis, of Steph. Collect., not of Marsham? 



Rather less than C. kispidus, and nearly of the same oblong 

 form, but with the thorax more distinctly contracted in front; 

 pitchy-black, with pale legs and attennae, and pretty densely 

 clothed with pubescence ; thorax rather thickly and finely punc- 

 tured ; elytra finely, but by no means thickly punctured, the 

 punctures rather oblong, the interspaces glossy. See next species 

 for further characteristics. 



6. Cis festivus, Panz., Gyll., Mellie, 1. c. p. 349, sp. 53, pi. 3, 

 f. 24. 



Fuscous, or fusco-testaceous, antennae and legs pale ; thorax 

 and elytra thickly punctured and well clothed with scale-like setae. 

 In size and form this insect comes very near the preceding ; it is, 

 however, a trifle less oblong, and differs more particularly in 

 having the punctuation rather stronger and more dense, especially 

 on the elytra. In C. jnjgmcBus, the interspaces between the 

 punctures (which punctures are rather oblong) would admit of 

 two, and often three punctures similar to those which exist, whilst 

 in C. festivus (where the punctures are round), there is scarcely 

 room for more than one puncture between the existing punctures : 

 here, moreover, the setae are decidedly stouter and more scale-like 

 than in C. pygmceus. The last-mentioned insect (the Marshamian 

 specimen) I have carefully compared with a specimen of C. oblon- 

 gus, presented by M. Mellie to the British Museum, an insect 

 which also agrees with a specimen in my own collection, named 

 by M. Mellie; and when these three specimens are compared with 

 specimens of C. festivus from M. Mellie, they present precisely 

 the differences which that author points out in his descriptions. 



The two last-mentioned species are each about one line in 

 length; the following is the smallest of the British species. 



7. Cisfuscatus, Mellie, 1. c. p. 352, sp. 55, pi. 4, f. 1. 



Scarcely ^ of a line in length, and of a narrow, elongate form, 



the thorax as broad as the elytra, not contracted in front, the sides 



gently rounded, the anterior angles obtuse, the posterior angles 



rounded: general colour fusco-testaceous; well clothed with short
