578 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiii., 



OOiMELA BIMACULATA, 11. sp. 



Reddish-castaneous, elytra blackish with a greenish gloss, and 

 with two reddish spots; most of antennae infuscated. 



Head with sparse and very feeble punctures, becoming slightly 

 more distinct on clypeus. Prothorax at base fully four times 

 as wide as long, sides rather strongly rounded in front; with 

 numerous, but very small punctures. Elytra wider than pro- 

 thorax at base, sides evenly rounded; with regular rows of rather 

 small punctures, interstices almost impunctate. Length, 2 2 mm. 



Uab. — Queensland: Port Denison (Macleay Museum). 



The character distinguishing this species from 0. ellipfica in 

 the table is a rather feeble one; but the two species differ as well 

 by the former being much smaller, rather more elongate, base of 

 elytra proportionately wider than base of prothorax, and to some 

 extent in the punctures. The spot on each elytron is fairly large 

 but not very sharply defined, and is placed at about the basal 

 third (on the third, and on part of the second and fourth inter- 

 stices), the extreme base of the elytra, and the suture near the 

 base are also somewhat obscurely reddish; there is a vague infus- 

 cation of the base of the head in both specimens. The abdominal 

 lamellte are rather short. 



OoMELA DISTINCTA, u.sp. (Plate xxix., fig. 9). 



Bright reddish-flavous; apical two-thirds of antenna?, lateral 

 margins of prothorax, a transverse subelliptic spot behind scu- 

 tellum, an oblique somewhat sinuous latero-median stiipe on each 

 elytron, a bisinuate subapical fascia, and most of the legs black, 

 or deeply infuscate. 



Head with some small punctures on clypeus, but elsewhere 

 almost impunctate. Prothorax almost four times as wide as l<-»iig, 

 sides feebly i-ounded on basal half, more strongly on apical; with 

 very minute punctures. Elytra not much wider than prothorax, 

 sides gently rounded; with regular rows of rather small punc- 

 tures, becoming much smaller posteriorly; interstices sparsely and 

 minutely punctate. Length, 3-3^ mm.
