Metriorrhynchns lugubris. 



(Plate XII. fig. 7.) 



Porrostoma lugubre, Waterh., Trans. Ent, Soc, 1877, p. 80, pi. ii. 

 figs. 69-72. 



Ater ; rostro nullo, clj-peo leviter emarginato ; elytris postice 

 paulo ampliatis, quadricostatis, interstitiis biseriatim foveolatis, 

 Butura marginibusque tenuiter ferrugineis. c5' • Long. 5 lin. 



Hub. Australia. 



Very close to hcemorrhoidalis. There is absolutely no rostrum. 

 The incrassated suture and margins of the elytra are dull rusty red. 

 The thorax is strongly angularly constricted in the middle, so that 

 the posterior angles diverge and are acute. 



Metriorrhynclius flavicoUis. 



(Plate XII. fig. 9.) 



Elongatus, parallelus, niger, supra opacus ; thorace flavo, obsolete 

 eeptemareolato, marginibus vix reflesis ; scutello flavo, medio in- 

 fuscato ; elytris quadricostatis, basi octocostatis, interstitiis creber- 

 rime biseriatim punctatis. Long. 5| lin. 



Hah. Batchian. 



Thorax gently convex on the disk, the mesial lanceolate areolet 

 deep and extending from the base to the anterior margin. Elytra 

 parallel ; each elytron vath. four complete strong costse, and four in- 

 termediate ones at the base ; the first and second of the intermediate 

 costae are traceable nearly to the apex of the elytra ; the interstices 

 are closely punctured. 



The ridges which divide the thoracic areolets are very obtuse. 



In the British-Museum collection are several specimens of a species 

 from Celebes which I have determined to be Lycus thoracicus, Fabr. 

 (Syst. EL, ii. p. 117), with which M. cyanopterus, Eedt., seems to be 

 synonymous. M. JlavicolUs differs from these in having the elytra 

 black, the thorax is more convex on the disk, the sides are less re- 

 flexed, and the mesial areolet is very strong and deep ; whereas in 

 M. thoracicus the mesial areolet is almost obliterated. The elytra 

 are very similar in sculpture, but in thoracicus the interval between 

 the third and fourth costae has two lines of very close transverse 

 punctures which meet in the middle of the interstice ; in JlavicolUs 

 the punctures in this interstice are less straight, transversely ovate, 

 and they do not meet so closely in the middle of the interstice.
