and the examination of two additional species of the genus 

 now leaves no doubt in my mind but that it is close to 

 JSsiotes, and consequently that it should be referred to the 

 Aterpides. 



Third interstice on each elytron (excluding 



.apex) with two tubercles or ridges ... tuberosus 



Third interstice with more than two. 



Glabrous along middle of under-surface mimicus 

 Not glabrous there angustus 



Cyllorhamphus angustus, n. sp. 



Black, antennae and tarsi reddish. Densely clothed with 

 rusty-brown, or chocolate-brown scales, becoming paler on 

 portion of under-surface. 



Head with minute, concealed punctures; with a shallow 

 inter-ccuiar fovea. Rostrum rather stout, subgibbous at 

 base ; basal two-fifths with concealed punctures, elsewhere 

 polished and with rather small but sharply defined ones. 

 First joint of funicle as long as three following combined, 

 second as long as two following combined. Prothorax slightly 

 longer than wide, sides somewhat rounded, apical third with 

 two strong parallel ridges, basal two-thirds with many 

 smaller, vermiculate ridges. Scutellum apparently sub- 

 oblong. Elytra long and narrow, about one-third wider than 

 prothorax ; with rows of large, round punctures, appearing 

 much smaller through clothing; third interstice with a dis- 

 tinct tubercle near base, an elongated ridge about middle, and 

 a small tubercle behind same ; fifth with three small tubercles 

 and a ridge conspicuously terminated at summit of posterior 

 declivity; seventh with one or two small tubercles and a 

 moderate ridge. Prosternum deeply notched in front, grooved 

 almost to hindmargin, where there is a fairly large, semi- 

 double fascicle. Metasternum elongate, with a distinct sub- 

 apical fovea. Femora stout; four front tibiae with fine, con- 

 cealed serrations on the lower-surface. Length, 7-9 mm. 



Hab. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 2723. 



Readily distinguished from the other species by the long 

 median ridge on the third interstice on each elytron. 

 Although most of the scales are entirely without lustre, those 

 on the suture frequently have a distinctly golden gloss; but 

 frequently the suture is partly abraded. The patch of paler 

 scales on the under-surface extends from the front of the 

 metasternum to the apex of the first abdominal segment 

 along the middle. On the elevated parts the scales are often 

 subsetose in character, and cause an appearance as of fascicles. 

 When the head has been abraded its punctures are seen to
