Coleopterous Suh-Family Byrsopince {Curculionidce). 85 



more or less faintly bisculate, with the dorsal margins subcostate ; 

 sulci often obsolete and the margins rounded. Prothorax dorsally 

 longer than broad, sides shghtly rounded, broadest about middle, 

 not dilated at apex ; upper surface with scattered shallow punc- 

 tuation, but in abraded specimens the punctures appear much 

 larger, deeper, and often subreticulate ; the central furrow is 

 variable in development, being usually shallow and almost in- 

 terrupted in the centre, but in some examples it is much 

 deeper and its margins are sometimes subcarinate ; the subapical 

 transverse impression is trifoveate, but these foveas also vary con- 

 siderably in depth, being sometimes very shallow; sides with a few 

 scattered punctures. Elytra suboblong, shoulders narrow, sides 

 gently rounded, broadest about middle, apical declivity abruptly 

 retuse ; upper surface with very shallow sulci containing rows of 

 punctures, of which 1, 2, and 3 are regular, while 4 and 5 are 

 usually somewhat confused, but these punctures are liable to 

 gradually disappear, either partially or completely, nor is this in 

 any way due to the scaling; interval 2 is slightly carinate posteriorly, 

 with a small but prominent tubercle at the top of the declivity, and 

 sometimes one or two smaller ones in front of it ; interval 3 is 

 scarcely raised even at the base : 4 strongly carinate, dentato- 

 tuberculate, and with a large, blunt, outwardly directed tubercle 

 at the top of the declivity ; 5 with only a low humeral carina ; 

 6 usually simply carinate, but sometimes bluntly tuberculate ; the 

 inflexed margins regularly and deeply punctato-sulcate, the punctures 

 deeper than on the disk and very rarely evanescent. Legs elongate, 

 with uniform light brown scaling, the femora with very short, sparse, 

 and depressed setae, the tibiae with longer erect setae ; tarsi long, 

 moderately setose, posterior pair with joint 1 slightly longer 

 than 2.

Type in the Copenhagen Univ. Museum (coll. Westermann) ; 

 type of suturalis in the Stockholm Museum; types of eximia and 

 vicar ia in the British Museum. 



In spite of its structural variability (which appears to be purely 

 individual in character), this species may be readily recognised by 

 its very distinctive facies and coloration. I have seen three examples 

 in which the tarsi are distinctly shorter than in normal specimens, 

 but this may perhaps represent an abnormal sexual character. The 

 type of suturalis can only be regarded as a very small variety of this 

 species, and vicaria is somewhat similar to it ; eximia appears to be 

 a normal example of amplexicollis.
