M. cequalifrons has sometimes the legs and antennae- 

 black, wholly or in part, but usually some parts are quite 

 distinctly red: that species, however, is much smaller than 

 0. raucus. 



Merimnetes ,equalifrons, Blackb. 



This species was described as being without a fine longi- 

 tudinal impression between the eyes. It, however, is really 

 present, although sometimes concealed by the clothing. The 

 scales are nearly always more or less ashen, but the elytra are 

 occasionally feebly sjDotted, and the prothorax has sometimes 

 a feeble dark stripe along the middle, and occasionally a very 

 feeble one on each side. The legs and antennae were not 

 mentioned, being presumably included under the word 

 '"piceus." In most of the specimens before me they are more 

 or less black, but occasionally are decidedly reddish, more 

 especially the tibiae and tarsi. The basal joint of the funicle 

 is about as long as the three following combined. 



SUBFAMILY AMYCTERIDES. 



Acaxtholophus extmius, Macl. (Cubicorrhynchus ) . 



A specimen in the Macleay Museum is labelled as Cubi- 

 corrhynchus exirnius, Macl., and although it is not the type 

 (this should be in the Australian Museum) it agrees with the 

 description, and was probably named from the comparison 

 with the type.< 4 > 



The species is evidently an A cantholophus. Its head and 

 prothorax certainly somewhat resemble those of several species 

 of Cubicorrhynchus, but so do those of many other species of 

 A cantholophus (irroratus, Macl., denticollis, Macl., and plani- 

 collis, Wath., amongst others). The shape of the head is 

 almost exactly as in irroratus, except that the conjoined 

 tubercles close to each eye are less prominent, and that the 

 eyes are more prominent. The prothorax has numerous 

 granules (not as numerous as in denticollis and planicollis) 

 on its disc, interspersed with a few of larger size. There is 

 a small conical tubercle on each side of apex, a less conspicuous 

 one on each side of base, and a larger conjoined pair on each 

 side near apex, but separated from apex by a deep impression. 



<4) Dr. Ferguson has kindly compared this specimen with the 

 type, and has written me as follows: — "I took the Macleay 

 Museum specimen of exirnius down to the Australian Museum 

 and compared it with the types. They are identical in regard to 

 tubercles, granules, etc., the only difference being that the types 

 are slightly wider and fuller in the elytra, and somewhat more 

 convex on ventral segments. These differences are in my opinion 

 sexual, and T should think that the Macleay Museum specimen 

 was the male, and the types females."
