Genus XXV, Ancisteogastek, Stal. 

 Stal, (Efv. Vet.-Ahad. Fori. xii. p. 349 (1855) ; Scudd. Bull. U.S. 

 Geol. Surv. ii. p. 253 (1876); Froc. Bost. Soc. Nat. Hist. 

 xviii. p. 288 (1876). 



Type, A. luctuosus, Stal, from Brazil. 



There is a single specimen of a new species from Australia in 

 the Museum Collection, with lateral hooks on the abdominal seg- 

 ments, as in Ancistrog aster, but differing much in the shape of 

 the body and forceps. I forbear to describe it, as it must belong 

 to a new genus, and I prefer to wait till more specimens are 

 obtained.
