Ne-w Genera and Species of Australian Hamiptera. 15 



posterior lo}>e which is depressed, especially in the middle. Scutel- 

 lum distinctly longer than broad, ahnost flat, punctate. Hemelytra 

 in the brachypterous form reaching base of last dorsal segment, 

 apical margin of corium rounded, clavus and basal half of corium 

 coarsely and thickly punctate, apical half of corium more super- 

 ficially and sparingly punctate, clavus with the puncturation 

 arranged in four rows, the commissure as long as the scutellum, 

 radial vein only reaching middle of corium, basal half of exocorium 

 with a single row of close punctures, the apical half fused with the 

 mesocorium owing to the abbreviated radial vein, membrane rudi- 

 mentary, appearing only as a narrow coriaceous strip attached to 

 the apical margin of the corium.. Pectus punctate. Abdomen 

 impunctate, last female dorsal segment with the apical margin 

 angularly sinuate in the middle, fourth ventral segment with two 

 sublateral glandular spots near base and a third one behind the 

 middle, fifth female, ventral segment very short in the middle. 

 Front femora somewhat incrassated, beneath in the apical half with 

 two small spines; middle and hind tibiae with a few stiff bristles; 

 first joint of hind tarsi twice as long as the two other joints together. 



Type: Rhypakochromus acuminatus, Dall. 



Allied to the Neotropical genus Esuris, Stal (as represented by 

 its type^), from which it differs by the very long rostrum, the longer 

 scutellum, the much longer hind metatarsus, and by having the 

 radial vein of the corium very distinct in its basal half; from the 

 Indian genus Lna, Dist., it is distinguished by the less incrassated 

 and less convex subglabrous body, the narrower, apically more 

 pointed head, the much less transverse pronotum, the narrower 

 scutellum, the (basally) very distinct radial vein, and by having 

 the basal joint of the antennae produced much beyond the apex of the 

 head. 



The species upon which tliis genus is fouink'd has slood for many 

 years in our catalogues among the " species incerti generis," and 

 Distant says nothing of it in his revision of the Hemiptera of the 

 British Museum, although he must have seen the type. 



Myocara acuminata, Dall. 



Queensland. 



Apart from some generic characters detailed above, I have little 

 to add to Dallas's description which fits the specimen before nie 

 so well that I feel sure of the identity. 



1 The Guatemalan A', purpurata, Dist., is possibly an Esurig, but that the North Ainerioaii K. 

 astanta, Barb., does not belon{f to this genus is clear from several characters.
