466 Mr. F. P. Pascoe on some Australian Colydiidae. 



JBothridercs merus. 



B, lutescens, subuitidus ; protliorace fortiter punctato, disco late depresso, 

 medio vix elevato ; elytris luteis. 



Hab. Melbourne. 



Luteoiis yellow, siibnitid ; bead with crowded, oblong punctures ; 

 eyes black ; protborax scarcely longer tlian broad, strongly punctm-ed, 

 anterior angles scarcely produced, tbe disk witb a large, broad, shallow 

 depression sligbtly raised posteriorly, Avitb a smooth ovate point in the 

 centre ; elytra luteous, rather more glossy than the protborax, striate- 

 punctate, the punctures rather small, the alternate interstices slightly 

 raised ; body beneath reddish brown, coarsely punctured ; legs and 

 antennae luteous brown. Length If line. 



From Bothrideres musivus this species may be distinguished by its 

 smaller size, paler and less glossy colour, and proportionally shorter 

 and less coarsely punctured protborax : in both the elytra are less 

 deeply striated, the interstices near the suture being very obviously 

 punctured. 



Bothrideres lobatus. 



B. fiilvo-luteus, subnitidus ; prothorace longitudinaliter corrugate, basi 

 bilobato, disco postice linea semilunari impresso ; elytris sutura mar- 

 gineque infuscatis. 



Hah. Sydney. 



Pale brownish yellow, subnitid; head sparingly pimctured; pro- 

 thorax slightly convex, rather broader than long, finely corrugated 

 longitudinally, a very distinct semicircular impression posteriorly, 

 between which and the base are two small diverging lobes ; elytra 

 slightly convex, the suture and lateral margins darker than the disk ; 

 body beneath pale brownish yellow, moderately punctured. Length 

 1^ line. 



The short and corrugated protborax, with its two raised and 

 thverging lobes at the base, render this sj)ecies easy of recognition. 



BotJirideres servus. 



B. fulvo-brunneus, subnitidus ; prothorace longitudinaliter corrugato, 

 postice linea subcm'vata impresso, basi late sulcato; elytris sutura 

 marginibusque infuscatis. 



Hab. Melbourne. 



Light yellowish brown, slightly shining ; head and protborax with 

 coarse pxractures, more or less confluent in a longitudinal direction, 

 giving the intervals a corrugated appearance, the latter nearly equal in 

 length and breadth, its anterior angles rather prominent, the posterior 

 impressed line only slightly curved, no anterior impression, a broad 

 shallow groove at the base ; elytra with the suture and margins darker 

 than the disk, striate-pimctate, the three lateral alternate interstices
