LOMAPTERA CASTANEA. 243 



minated ou the outside by three teeth at the posterior and 

 by two teeth at the intermediate pair. 



The described female specimen has been captured by 

 Mr. Colffs in the island of Sumbawa and presented to the 

 Leyden Museum by his Excellence J. W. van Lansberge. 



This new species seems to be allied to Lomaptera timo- 

 riensis Wall. ^) and to Lomaptera hrunneipennis Thorns. ^) , 

 both from the island of Timor. According to the des- 

 criptions of these species which are not represented in the 

 Leyden Museum , it differs from the first by the sculpturing of 

 its upper surface being much more dense , the elytra being 

 moreover not punctate-striate but transversely striate, and from 

 the second by its different shape, being attenuated towards 

 the apex, by the want of the round nodosity on the mid- 

 dle of the head , by the sculpture of the pygidium which 

 is transversely striate all over , etc. 



'i. Lomaptera castanea (v. Voll. in Mus. Lugd. Bat.), 

 sp. n. cf . 



Under this name Mr. Mohnike in his »Uebersicht der 

 Cetoniden der Sunda-Inseln und Molukken" ^) mentions a 

 Lomaptera in the Leyden Museum , but regards it as a 

 very young specimen of L. timoriensis Wall. , which has 

 only just developed into the perfect state and in which 

 the deposition of pigment is not yet quite completed. 



Since then Mr. Thomson , who possesses the type of X. 

 timoriensis Wall. , has published *) some characteristics of 

 this species which were not mentioned by Mr. Wallace, 

 and these have convinced me that the specimen of the 

 Leyden Museum belongs to an undescribed species which 

 may be closely allied to Lomaptera hrxinneipennis Thoms.,
