laterally sinous thorax, which is usually somewhat brightly metallic, 

 more oval elytra. shorter and stouter limbs, etc.; and the small size^ 

 brightly metallic thorax, and rough punctuation of the elytra of 

 D. rugipennis, Mots. {auricoUis, C. 0. Wateehouse), which occurs at 

 Hakodate in the North-eastern island Yesso, render any com- 

 parison with that species unnecessary. 



I have much pleasure in dedicating this insect to Mr. Lewis 

 (who practically also discovered D. rugipennis, as he described it 

 to me in a letter from Japan before the publication of the late 

 Colonel Mütschoulsky's description); for, supposing that future 

 explorers ;may detect. satisfactory links between it and blaptoideSy. 

 it will still apparently deserve recognition as a well marked race. 

 It may, however, be observed, that during a period of nearly eight 

 years Mr. Lewis and his native collectors have especially sought 

 for Damaster in any form in very many localities." 



Auch Waterhouse (2) hebt den Unterschied zwischen 

 der großen Form des Südens, welche er ebenfalls mit dem D. 

 hlaptoides Koll. identifiziert, und dem kleineren leimsii Rte hervor 

 und betont, daß man trotz der Geringfügigkeit des Unterschiedes an 

 größeren Reihen von hlaptoides und leivisii doch die^on Eye an- 

 gegebenen Merkmale leicht erkenne und daß auch die Eingeborenen 

 die beiden Formen voneinander unterscheiden. Er sagt: 



„The difference between this form and D. hlaptoides are very 

 slight, and I scarcely recognize in Mr. Lewis's specimens the dis- 

 tinguishing characters drawn by Mr. Rye from the longitudinal line 

 of the thorax and tiie legs. The Japanese themselves, however, dis- 

 tinguish the two forms, and when a long series of specimens of each 

 are compared, the smaller size, more slender figure and shorter mucra 

 of B. leu-isii are sufficiently conspicuous. In size it vai'ies from 

 1 in. 6 lin. to 1 in. 8 lin." 



In ähnlichem Sinn äußert sich H. W, Bat es (4). Er zitiert 

 die Worte Lewis' (3), D. leivisii sei „a half-starved-form. so to speak, 

 of D. hlaptoides" und schreibt selbst: „Leivisi is an olfshoot of 

 hlaptoides rendered smaller by the dryness of the area it inhabits, 

 as compared to the distiict of luxuriant Vegetation in which hlaptoides 

 dwells ; it is not a variety swing to a dry mountain atmosphere, but 

 a variety pertaining to a dryer, lighter soll, of the same elevation." 



Zusammengefaßt sind die von Rye für letoisi im Verhältnis zu 

 goliath angegebenen Merkmale folgende: Kleinere, schmäch- 

 tigere Gestalt, kürzerer Prothorax mit stärkerer
