Mr. W. L. Distant on Australasian Pentatomidse. 591 



rior angles subprominent, lateral angles subprominent and 

 obtusely toothed, anterior margin concave, callous, and poste- 

 riorly denned at its middle area by a transverse series of 

 punctures, posterior margin almost straight, the posterior 

 angles very slightly roundly subprominent; scutellum as 

 long as broad, depressed a little beyond base, apex rounded; 

 corium about as long as head and pronotum together, the 

 costal margin a little convex ; membrane passing abdominal 

 apex, veins numerous and longitudinal, sometimes one or 

 two furcate at apex; rostrum extending to the posterior 

 coxae, first joint reaching base of head, second slightly 

 passing anterior coxae, third reaching intermediate coxae, 

 sternal process not reaching apex of presternum, anteriorly 

 roundly obliquely depressed, posteriorly excavately bispinous 

 for the reception of the apex of an abdominal basal tubercle; 

 legs of moderate length, tarsi somewhat long, posterior tarsi 

 with the basal joint almost as long as the remaiuing joints 

 together; odoriferous orifice distinctly curved. 



Allied to Pegala, Stal *, but with the head broader and 

 apex truncate, eyes distinctly removed from the anterior 

 angles of the pronotum, proportional length of the antennal 

 joints different, apex of scutellum rounded, not acute. 



Koogobatha mirabilis, sp. n. 



Colour bright and shining ; head ochraceous, lateral 

 margins narrowly, a broad central longitudinal fascia (broken 

 posteriorly), and the base broadly black; antennae black; 

 pronotum ochraceous, with three prominent black spots, 

 two (transverse) on anterior area, and the third rounded at 

 middle near base ; scutellum black ; corium black, its basal 

 angle ochraceous, and with a somewhat large reddish- 

 testaceous discal patch on the posterior area ; membrane 

 black ; body beneath pale ochraceous, a central rounded 

 spot on each side of the process on mesosternum, a trans- 

 verse spot on each side of the sternal segments, and four 

 longitudinal series of spots to abdomen beneath (the largest 

 on each side of disk) black ; legs ochraceous, a broad annula- 

 tion on apical halves of femora, the whole of the tibiae and 

 the tarsi more or less black ; rostrum black ; head finely 

 transversely wrinkled on each lateral area ; pronotum very 

 finely and obscurely punctate ; scutellum sparsely punctate, 



* In reference to the structural characters of Pegala, StSl, those 

 given by Haglund of the typical species P. guttula (Stett. ent. Zeit. 1868, 

 p. 159), on which the genus is founded, should be consulted.
