68 HERMETIA BATJANENSIS. 



Westwood's figure of Massicyta hicolor (1. c. pi. 1 , f. 1). 

 My specimens are by no means similarly shaped , though 

 the first abdominal segment may be somewhat narrower 

 than the following ones, as is mentioned in my descrip- 

 tion. Perhaps Walker would in later times not have stuck 

 closely to this character of his genus Massicyta, the only 

 one by which it is distinguishable from Hermetia. Surely 

 the specimens mentioned by Osten Sacken are identical 

 with mine. 



Closely allied to H. hatjanetisis , if not identical with 

 it, may be H. Melanesiae Bigot (Ann. soc. ent. de France , 

 5th ser. IX. 1879. 262. 4); however I do not see the 

 yellow hairstripes on the thorax, mentioned by him, and 

 which may have been rubbed ofi in my less sound speci- 

 mens. Moreover they have the scutellum wholly yellow , 

 whilst in the description of H. Afelanesiae it is called yel- 

 low with a black base (the rather ample diagnose does 

 not mention this). 



If afterwards by a comparison of the typical specimens , 

 Massicyta cerioides Walk. , Hermetia Melanesiae Big. and 

 my H. batjanensis might prove to belong to one and the 

 same species , the name cerioides Walk, must be accepted , 

 as being the oldest. 



19. Hermetia armata, n. sp. 



Nigra; scutello bispinoso ; abdominis incisuris 2 et S 

 aiireo-tomentosis ; ventre rufescente; pedibus piceis , tibiis 

 tarsisque flavescentibxis ; alis flavidis. — Q. Long. 17 — 19 mm. 



This species has all the characters of the genus Herme- 

 tia , excepting that the scutellum is armed with two spines, 

 a character upon which later most likely a new genus will 

 be founded ; for the present however , such a separation 

 does not seem to be urgent. 



Black ; head and thorax a little shining. Head broader 

 than the thorax; front about one fourth as broad as 

 the head , flat , with a longitudinal groove ; face convex
