214 THE GENERA AND SPECIES OF AMYCTERIDuE, 



The shape of the anal forceps of the male is very remarkable 

 in this species. It is long, placed horizontally, much arcuated, 

 not thick, and becoming suddenly thinner near the apex, where 

 the point of tlie left side branch rests upon the other. The 

 knife-like process of the inner edge is also remarkably long in 

 this species, that on the right side completely overlapping the 

 other.

Oblongo-elliptica nigra nigro-setosa parce cinereo-squamosa, 

 thorace confertim subtiliter tuberculato, elytris reticulato- 

 punctatis interstitiis costatis alternis elevatioribus apice 

 mucronatis. 



Mas : forfice anali longo gracili acuto vix arcuato. 

 Long. 11 lin., lat. 4 lin. 

 Hab. Ipswich, Queensland. 



The distinctly reticulated elytra, and long sharp anal forceps 

 of the male, serve at once to distinguish this species from any 

 other. 



I have named it after its discoverer, Mr. Masters.

 Amycterus reticulatus Boisd., Voy de I'Astrol. II., p. 384. 



"Oblongo-elliptica nigra parcissime squamosa, thorace subtiliter 

 tuberculato tuberculis postice medio minus crebre obsitis, 

 elytris seriatim crebre foveatis interstitiis subcostatis sub- 

 Isevibus setis brevibus nigris tenuiter armatis."

If I had not found the original insect named by the late Mr. 

 MacLeay in his collection, I should certainly never have been 

 able to identify it from the description given of it by Dr. Bois- 

 duval, which is in these words : — " Ater oblongus, thorace grani- 

 fero, elytris granulatis subcostatis subreticulatis." I have only 

 seen the female of this insect, it is somewhat like the female of
