24 IJuiic, 1876. 



other coarse basal punctures, and a few others, scattered on the surface. Scutellura 

 moderately large. Elytra rather rounded at the shoulders, which are a good deal 

 broader than the base of the thorax, rather densely clothed with a long, fine 

 pubescence, and with eight rows of coarse punctures, which are placed in depressed, 

 not well defined strise. Legs red. Tarsi slender, basal joint of hind tarsus quite 

 as long as the two following together, spurs of tibiee minute. 



Sent from Auckland by Mr. Lawson. 



Obs. — I have at present before me only a single female of this 

 very remarkable species, which is intermediate in appearance between 

 Scydmcjeims and Catops ; I noted that a male which I formerly ex- 

 amined, had the two basal joints of the front tarsi dilated, and a 

 minute supplemental apical segment to the hind body ; my recollection 

 on this latter point is not very trustworthy.

Antennse similarly formed to those of C. thoraciciis, but rather less elongate. 

 Thorax greatly narrower than the elytra, transversely convex, as well as depressed iu 

 front, the sides sinuate and contracted behind the middle, the hind angles rectangular 

 but not well defined, it bears an irregular bright yellow pubescence, and is impunctate, 

 except for a series of large punctures, about seven in number, along the base. 

 Elytra of a sliining chestnut colour, with a similar pubescence to that of the thorax, 

 with a well marked sutural stria, and impunctate, except for some coarse punctures 

 at the shoulders. In the male, the basal joints of the front and middle tarsi are 

 distinctly dilated, and the apical ventral segment is very broadly emarginate, the 

 margins of the cut away part much elevated. 



We are indebted to Mr. Lawson also for this species. 



Obs. — This insect has quite the facies of a Eumicrus (in the 

 Scydmcenidee), and I had formerly referred it to that family ; but the 

 front coxal cavities, which are closed behind in the same manner as in 

 Catops, indicate that it cannot be classed with the Scijdm^nidce. It is 

 a remarkable fact that two insects, so distinct from other known forms, 

 and so closely related inter se, as this species and C. thoracicus appear 

 to be, should yet be so dissimilar in appearance from one another.
