laterally sinous thorax, which is usually somewhat brightly metallic^ 

 more oval elytra, sliorter and stouter lirabs, etc.; and the small size^ 

 brightly metallic thorax, and rongh pimctuation of the elytra of 

 D. rugipennis, Mots. {auricoUis, C. 0. Wateehoüse), 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 

 Colone! Motschoulskt's description) ; for, supposing that future 

 explorers 'may detect satisfactory links between it and UaptoideSy 

 it will still apparently deserve recognitiou 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 Wateehoüse (2) hebt den Unterschied zwischen 

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

 Uaptoides Koll. identifiziert, und dem kleineren leivisii Eye hervor 

 und betont, daß man trotz der Geringfügigkeit des Unterschiedes an 

 größeren Reihen von hlaptoides und leivisii doch die von 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. Uaptoides are very 

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

 tinguishing characters drawn by Mr. Eye from the longitudinal line 

 of the thorax and the legs. The Japanese theraselves, 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 mucro 

 of D. leivisii are sufficiently conspicuous. In size it varies 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. Uaptoides^'' und schreibt selbst: „Lewisi is an offshoot 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 soil, of the same elevation." 



Zusammengefaßt sind die von Eye für leivisi im Verhältnis zu 

 goliath angegebenen Merkmale folgende: Kleinere, schmäch- 

 tigere Gestalt, kürzerer Prothorax mit stärkerer
