442 B. Brunetti : Oriental Bombylidce. [Vol,. II, 



N.B. — With this species I have identified almost with cer- 

 tainty three 2 $ in the Indian Museum (two from Tenasserim 

 and one from Mergui in Lower Burma). 



The under side of the abdomen is nearly wholly y^//oz£;-haired, 

 as described by Doleschall^ but the brown colour of the wing crosses 

 the upper basal part of the discal cell, whereas Osten Sacken (Berl. 

 Knt. Zeits., xxvi, 112) says it should not encroach upon it. 



19. oenomaus, Rond., 1875, Ann. Mus. Gen., vii, 453. 



Loc. — Borneo (Sarawak) [t. Rond.] ; Philippines [t. Os. Sack.]. 

 Type in Genoa Museum. 



N.B. — In the Indian Museum are three specimens which 

 appear to be this species (from Sikhim and Mergui), varying 

 in size from 9 to 17 millimetres, Rondani's measurements being 

 18 mm. Both Rondani and Osten Sacken sa}^, belly with ' ' yellow- 

 ish white " and " yellow " pile, respectively, but in the above 

 examples it is only whitish ; moreover, the 2nd posterior cell is no 

 narrower at the distal than the proximal end (but is contracted 

 in the middle, as occurs in several species) ; and finally, the white 

 spots at the tip of the abdomen are four in number, and do not 

 resemble cross-bands. I still believe they are this species. 



An undescribed " sp. nov." of Bigot's in the Indian Museum 

 {argyura : the "type" is headless and in bad condition, but 

 there are two other specimens, evidently of the same species, 

 one of which possesses a head) closely resembles oenomaus and 

 may represent the true form. In this the silvery white pile on 

 the abdomen tip is very brilliant, and takes the form of a broad 

 spot, extending over all the last three segments. 



The pile on the belly is white, the 2nd posterior cell of uni- 

 form width, and the brown band on the wing is rather more re- 

 stricted and more clearly defined than in the specimens I have 

 identified as cenomaiis.

Notes on the genus HYPERALONIA. 



It is quite impossible to separate, in any brief manner, the 

 above twenty species into groups, yet I fully believe they are all 

 or nearly all good species. On Mr. Austen's information that they 

 possess four submarginal cells I have included under this genus 

 the following species of Walker: "Anthrax"' confirmata, conibi- 

 nata, devecta, demonstrans and lati fascia. Of devecta I have since 

 found a named example in my own collection. 



The wing-marks appear to me to be reliable characters, as 

 they have been found constant in specimens of the same species 

 examined by me. The following species have been seen by me 

 either in the Indian Museum collection or my own : tantalus, P\,
