marks consisting of spots more or less united ; each has four sharply raised costte, 

 and a series of crenate punctures runs along each side of each costa ; the costee have 

 fine depressed flavescent setae on their summits, and the serial punctures also bear 

 similar depressed setae, which are arranged so that their tips touch the costse, and 

 thus form a sort of minute, angular, reticulate pattern. 



Ahurei Bay, Eap-a (Oparo) Island. 



This is allied to a New Zealand species, B. insularis, AVhite. 



KEKLASMENUS, n. gen. 



Tarsi triarticulati. Antennce decemarticulatce, rlava uniartimlata, apice 

 constricto et pubescente. 



Antennse with the first joint short, concealed beneath the side of the head, 2nd 

 joint stout, rather longer than broad, 3rd elongate and slender, the following six 

 nearly similar to one another, 10th joint rather long, receiving the true terminal 

 joint, which projects beyond it as a pubescent point. Eyes moderately large, very 

 convex, moderately finely facetted, bearing a few erect sette. Clypeus truncate in 

 front, emarginate on each side. Labrum prominent, transverse, truncate in front. 

 Thoi-ax subquadrate ; front coxa) moderately widely separated, prosternal process 

 projecting very little beyond them, scarcely at all bent upwards. Mesosternum 

 slightly separating the middle coxse ; metasternum elongate. The five ventral seg- 

 ments subequal in length. Epipleura quite horizontal and flat, rather broad, con- 

 tinued to the suture at the apex without diminishing in width. Legs rather stout ; 

 tibise abruptly bent at a right angle immediately outside the articulation, finely and 

 minutely pubescent externally, not hispid. Ist joint of tarsi rather longer than 

 2nd, which is small, 3rd much longer than the 1st and 2nd together. 



The occurrence of a Golydien with three-jointed feet is of con- 

 siderable systematic interest, but I have already intimated that this 

 discrepancy is not of family importance in the Golijdiidcs, and Kek- 

 lasmenus seems to completely demonstrate this, as in other respects it 

 appears to be an oi'dinary Colydien, allied to Bitoma and Cicones. It 

 is true that the antennae are a little aberrant, but this is of little 

 importance, for in Pycnomerus we have already a case where the 

 antennae, from being 11-jointed, become in a series of species gradually 

 10-jointed, by the suture between the 10th and 11th joints becoming 

 more or less obsolete; and as regards this point KekJa^menus may be 

 looked on as a form having either 10-jointed or 11-jointed antennae, 

 according as the pubescent extremity is treated as a separate joint or 

 the reverse. 



The tarsi appear to me only 3-jointed ; nevertheless, I can, I 

 think, see on the hind feet the traces of a division of the basal joint, 

 so that the 3-jointed tarsus is probably due to a diminution in size of 

 the true basal joint, and a concomitant consolidation with the true 

 second joint,, which in this manner becomes the basal joint.
