 Among the Cicindelinse collected by Mr. W. Schultze, of Ma- 

 nila, are to be found a great many very interesting species. 

 They are as follows : 



Collyris speciosa Chaud. Mindoro, near Abra de Hog. 

 Collyris similior W. Horn. Mindanao, Momungan, and Zamboanga. 

 Collyris chaudoiri W. Horn. Biliran Island. Punctures on the basal and 



apical thirds of elytra less dense and of smaller size than usual. 

 Collyris emarginata. Mindanao, Zamboanga. 

 Collyris albitarsis. 

 Tricondyla aptera subsp. globicollis. Polillo Island; Mindanao, near Su- 



rigao.
