Genus Holoptilus. 
locality of the typical species.* General Hardwieke’s insect was 
from Nepaul, and Dr. Horsfield also found it in Java; and I 
have now to add another species from Van Diemen’s Land. I am 
also able slightly to characterize a fourth species from Java in 
the Royal Collection of Berlin, hoping to receive a figure and 
more ample description of it from Dr. Burmeister in time for 
publication. 
Notwithstanding the variations in structure which exist in the 
species, I am inclined to retain them in the same genus on ac- 
count of their great general relation together, although I fear I 
shall be blamed for retaining such diversities of organization. It 
will be convenient, however, to establish a sub-genus for the re- 
ception of the Indian and Australian species, on account of the 
strong nervures of the hemelytra. I would for these species have 
retained Gray’s name, Philocerus, but it had been long previously 
employed in Entomology. 
Sub-genus 1. Holoptilus, stricte sic dictus. 
Antennce, ut videtur,'j~ 3-articulatae ; articulo 2do longissimo 
curvato, setis in triplici serie dispositis ; articulo 3tio minuto. 
Caput postice tuberculatum. Hemelytrorum membrana ner- 
vis obsoletis ; alee minutissimae, aveniae ; tibice posticae setis 
in triplici serie dispositis. 
Species 1. H. ursus. (Plate XXII. Fig. G.) 
Fuscus, albo-sericeus ; hemelytris albis, macula magna versus 
basin alterisque tribus minutis ad marginem externum fuscis, 
setis fuscis, serie intermedia antennarum et tibiarum postica- 
rum alba. 
Long. corp. (alis exp.) lin. 2|. Expans, hemelytr. lin. 4. 
Habitat apud Cap. Bon. Sp. Delalande. 
In Mus. Reg. Paris., Berol. et nostr. 
* In the Crochard edition of the Regne Animal an indifferent figure is pub- 
lished of Holoptilus ursus ( Insectes , pi. 92, fig. 2), and in the text New Holland is 
given as its locality ; but my specimen, which I obtained from the collection of 
the Jardin des Plantes is ticketed by IM. Audouin himself “ Cap. de b. esper. 
Delalande.” The Cape is also given as its locality in the Encyclnpedie Method., 
and I am informed that Mr. Macleay obtained specimens from the Cape in a large 
collection which he purchased from M. Verreaux. 
t Burmeister, who gives H. ursiis as the type of the genus, describes the an- 
tennae as four-jointed. Saint Fargeau, however, gave them in that species as 
three-jointed, and in my specimen they are also three-jointed and exhibit no ap- 
pearance of mutilation.
