38 E. Bergrotk: 



Fam. REDUVIIDAE. 



27. POKCILOBDALLUS FORMOSUS, Stal. 



Bagot's Creek ; Tempe DoAvns. 



The colour of the upper side of the head is in suiue specimens as 

 described by Stal, but usually it is black, excluding the part 

 situated before the antennae, which is red with the clypeus blackish ; 

 the postocular part has above a yellow median line. The abdomen, 

 which was lacking in the single type-specimen described nearly GO 

 years ago, is black with the broad, rather strongly rounded con- 

 nexivum from its base to the middle of the sixth segment above and 

 beneath, and a median ventral spot of very variable size red; this 

 ventral spot sometimes small, placed at base of third segment, some- 

 times large, reaching from apex of second to near apex of fifth 

 segment. 



28. Havinthus longiceps, Stal. 



Finke River near Bend ; Dalhousie Springs. Tdracowra. Illamurta. 



This species is extremely variable in colouring and in the develop- 

 ment of the granulation, and it is hardly possible to describe its 

 varieties as they are connect/ed by numerous transitional links. 



Oncockphalus confusus, Reut. 



Bagot's Creek. 



Fam. VELIADAE. 



30. MiCROVELlA AUSTRALICA, n. sp. 



Oblong, black with a cinereous bloom, a transverse apical spot to 

 pronotum and the margin of its produced posterior part, con-

 luteous, a longitudinal line to pronotum velvet-black, ac^etabula 

 and legs testaceous, the latter here and there infuscated. Head as 

 long as broad, rostrum scarcely passing prosternum. dark tes- 

 taceous, last joint piceous, antennae blackish, first two joints, 

 except apices, dark testaceous, second joint as long as first, third a 

 little longer than second, fourth the longest, slender. Pronotum 

 rugulosely punctate behind the middle, lateral angles obtusely a
