Endomychus, It is not, however, of itself a generic character. Some- 

 what similar organs exist in one species oi Encymon (see Notes from 

 Genoa Mus. vol. ii. 1885, p. 519) and in certain genera of 

 Languriides. 



Cyanauges, Gorham. 



To this genus the North-American Endomychus higuttatus of 

 Say and llycetina limbata, Horn, Ijelong. The latter is the insect 

 alluded to by me (End. Kec. p. 64) as Endomychus qnadripunctatus, 

 llliger, and is the E. quadrinotatus of Dejean's Catalogue, p. 464. 

 It is wrongly given in Gemm. and Harold's Cat. as a synonym of 

 E. bigvttatus, from which it is specifically distinct. It occurs, 

 according to Horn, in the State of California; I have seen it from 

 Nevada {Morrison). I am not inclined to lay much stress npon 

 the geneiic difference between these species and Endontychns. If we 

 except the two North- American species mentioned, the other Asiatic 

 speciiS are very differently coloured, and are narrcjwer and more 

 convix. Perhaps after all some one may discover better points of 

 distinction than those I have given for Cyanauges.

 (Plate LIII. fig. 5.) 



Hab. Main Island: Kashiwagi, Nikko, and Fukui. Yezo : 

 Juisai and Sapporo. 



Described from a unique example from Kawatchi. 



Mr. Lewis informs me this insect was found commonly in 1881, 

 in the mountains, on a species of Agaricus allied to A. atrocceruleus, 

 in Kiushiu and on the Main Island, in June. In April only the 

 remains of former generations were to be found. 



2. Cyanauges plagiatus, n. sp. (Plate LIII. fig. 6.) 



Niger, nitidus ; elytris singulis plagia lata nee murginem necsuturam 

 attingente, abdomineque {segmento basali excepto) castanets. 

 Long. 5 millim. 



Hab. Kiushiu : Yuyama and Ilitoyoshi. 



Var. Plagia intervvpta, maculas duas aurantiacas formante. 



Hab. KiusHru: Iligo. 



The avera'ie specimens are a little Lirger than C. gorhami, but 

 the general f, rm and punctuation is similar. Head and thorax 

 shining black, the latter a good deal narrower than the elytra at its 

 base, the sides narrow to the front angles, which are prominent and 

 subacute. The elytra are oblong-ovate, distinctly punctured. Most 

 of the examples have the margin narrowly, the suture widely for 

 half its length, more narrowl) behind, and the apex widely black, 

 thus leaving a wirle discoidal plagia yellow. Occasionally, as in 

 examples from Hi o, this is divided by the ground-colour of the 

 elytra leavi.ig only two yellow spots, one humeral occupying the 

 callus, the other a little j)ast the middle, ill-defined, yellow. Tne 

 breast and whole of the basal segment of the abdomen black, the 

 remainder of the abdomen chestnut-yellow. Many examples were
