In no way is typical grisea a link between its var. patruelis and 

 kaonohi, as apart from the development of the pronotal spines, 

 the first two are identical in form. 



(a) Oechalia grisea, male • 



pygophor; 



(b) O. Uaonolii, the same. 



N. B,— In both, the ventral 

 surface of the pygophor is 

 uppermost. 



I have not seen any females of kaonohi, but that of grisea is 

 sufficiently distinct from consocialis, its 7th urosternite being 

 more deeply emarginate apically, and the apilolateral plate of 

 the pygophor is distinctly longer and more prominent. 



Note on the Synonomy of two Hawaiian Beetles. 



BY G, W. KIRKALDY. 



In Mr. Champion's notice in the Ent. Mo. Mag (2), xx, 103-4, 

 (May, 1909), "Notes on Cossonidae," it is stated that the beetle 

 Thalattodora insignis Perkins (1900) found in a log on the 

 beach at Kauai [Kanai! Champion] is a synonym of Dryotribus 

 mimeticus Horn, 1873, from South Florida. This beetle is also 

 recorded from N. W. Australia; "Nyew-tew" Isl, China; by 

 Champion (Ent. Mo. Mag., (2), xx, 123, June, 1909). The 

 Australian examples "were found under driftwood on a sandy 

 beach." In the latter paper, Champion also^ synonymizes Halox- 

 cniis Perkins, (1900), from Molokai and Canai, with the Flori- 

 dan Macrancylns Leconte (1876).
