 REMARKS ON HYMENOPTERA AND COLEOPTERA. 



BY 



C. RITSEMA Cz. 



Uymenoptera. 



1. I have proposed (cf. DeyroUe's Naturaliste. VI. p. 559, 

 15 Nov. 1884) to substitute the generic name Darala 

 Ritsema (Notes Leyd. Mus. VI (1884). p. 81, Hyrae- 

 noptera: Larridae) nee Darala Walker (List Lepid. Ins. 

 Brit. Mus. IV (1855). p. 886, Lepidoptera : Bombycidae) 

 by JPatara. 



2. Xylocopa Forhesii Kirby Q, from the Timor-Laut Islands 

 (Proc. Zool. Soc. London. 1883. p. 344) = Xylocopa 

 coronata Smith (Journ. Proc.' Linn. Soc. Zool. V (1861). 

 p. 135) from Kaioa (Brit. Mus.) and Halmaheira, Bat- 

 jan and Ternate (Leyd. Mus), the different iridescence 

 of the wings, the only dij^erence mentioned by Mr. 

 Kirby , not being of specific value , as the specimens in 

 the Leyden Museum , although doubtless belonging to 

 one and the same species, show considerable variations 

 in that respect. 



Coleoptera. 



1. I propose to substitute the generic name Metallactus 

 Albers (Deutsche Entom. Zeitschr. XXVIII (1884). p. 

 303, Coleoptera: Lucanidae) nee Metallactus Suffrian 

 (Linnaea Entom. XVI (1866). p. 248, Coleoptera: 

 Chrysomelidae) by Mefallactuhis. 



2. I propose to substitute the generic name Oxyrhynchus 

 Schönherr (Disp. Meth. 1826. p. 77, Coleoptera: Cur- 

 culionidae) nee O.ryrhyiichus Spix (Test, et Ran. Bras. 

 1824, Amphibia: Bufonidae) by Cryptoderma.
