50 LYCIDiE. 



Metriorrhynchus lugubris. 



(Plate XII. fig. 7.) 



Porrostoma lugubre, Watcrh., Trans. JEnt. Soc, 1877, p. 80, pi. ii. 

 figs. 60-72. 



Ater ; rostro nullo, clj'peo leviter emarginato ; elj'tris postice 

 paulo ampliatis, quadricostatis, interstitiis biseriatim foveolatis, 

 sutura marginibusque tenuiter ferrugineis. c? . Loug. 5 lin. 



Ilab. Australia. 



Very close to hcemorrJioidalis. There is absolutely no rostrum. 

 The incrassated suture and margins of the elj'tra are dull rusty red. 

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

 the posterior angles diverge and are acute. 



Metriorrhynchus flavicoUis. 



(Plate XII. fig. 9.) 



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

 septemareolato, marginibus vix reflexis ; scutello flavo, medio in- 

 fuseato ; elytris quadricostatis, basi octocostatis, interstitiis creber- 

 rime biseriatim pxmctatis. Long. 5| lin. 



Hab. Batchian. 



Thorax gently convex on the disk, the mesial lanceolate areolet 

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

 parallel ; each elj-tron with four complete strong costee, 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 sptecimens of a species 

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

 (Syst. El., ii. p. 117), with which 31. eyanopterus, liedt., seems to be 

 synonymous. M. jlavicollis drffers from these in having the elytra 

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

 fiexed, 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 costoe has two lines of very close transverse 

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

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

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



Metriorrhynchus kirschii. 



Dictyopterus lineatus, Kirsch, Mitth. d. k. zool. Miis. zu Dresden, 1875. 

 Ater, supra opacus ; thorace septemareolato ; elytris parallelis,
