3i1S REVISION OP THE AMTCTEEIDES^ 



Tlie above description of the male is taken from a specimen in my own 

 collection. The male described by Maeleay, now in the Macleay Museum, is not 

 the same species as the female described, but belongs to the next species — II. 

 maeulatus Macl. It may be that the male should be regarded as the holotype 

 of the species, in -which case tlie name macnlatug would fall as a synonym of 

 furcatus, while a new name would be required for the present s|ieeies. I do 

 not propose to follow this procedure as it is abundantly evident from the specific 

 names, and also from his comments, that Macleay distinguished the two species 

 on the differences between the two females, and I would suggest that this sex 

 be regarded as the holotype of II. furcatus, tlms preserving both names. 



The two species are closely allied but the clothing is quite distinct, and the 

 general sculpture is rougher in 77. furcattis. 



Both species may be distinguished from the other members of the gen>is by 

 the small sujDraorbital tubercles. They are also separable from the other 

 species on the fm-m of the submentum. Tn 77. furcatus and H. maeulatus the 

 buccal emargination is straight wheieas in the other species there is a strong 

 tongue-shaped median lobe projecting into the aperture from the submentum. 

 This lobe occurs also in Anascoptes and in other widely separated genera, and 

 its significance is uncertain. The submentum was not examined in 77. aculeatus. 



Hyborrhynchus jiaculatus Mad. 



Macleay, Trans. Eut. Soc. N.S. Wales, i.. 1865, p. 207. 



c?. Small, narrow. Clothed with dark brown pubescence, prothorax with a 

 median golden brown vitta, sides with a dense white vitta above; elytra with 

 golden brown vittae between the rows of tubercles and on lateral interstices, the 

 lowest interstice with a white vitta, deeli\dty with a single, mainly white, \itta on 

 each side. 



Head wfth tubercles as in 71. furcatus; rostrum similar but with external 

 margins less strongly angulate, and basal tubercles slightly smaller. Antennae 

 with the fii-st two joints of the funicle subequal. 



Frotliorax nuich as in 77. furcatus; sul)median tubercles smaller, not con- 

 joined ; lateral tubercles somewliat more acute. 



Elytra pai'allel-sided ; ajx'x widely emarginate. moi-e strongly mucronatc on 

 each side; puuctui'cs more regular, in definite striae; with three rows of tubercles, 

 first row on third interstice composed of 7-0 tubercles, for the most part small, 

 becoming larger posteriorly, the basal tubercle also slightly larger, the apical 

 much larger and acutely conical; second row with 6-7 erect, conical tubercles, the 

 basal slightly larger than the ones following it, the two last larger and acute, 

 the apical reaching a lower level than that of fii-st row; seventh interstice with a 

 conical infra-humeral sjiine and one or two small granuliform tubercles. 



Venter flat, ratlier spai-sely clothed with brown, with .-i ineilian while vHta 

 on the basal segments. Legs simple. 



9. Thickly clothed with light brown pubescence, strongly maculate with 

 white, appearing obscurely vitiate from certain directions. 



Head, rostrum and prothorax as in male. 



Elytra broader, with tubercles much debased, the first row about 8 in m\m- 

 ber, hardly larger than granules, the last longer and conical; second row with 

 about fl, mostly small granules, the basal tubercle larger, the la.st two larger 

 and more conical, the apical one in line with those cm seventh interstice; third 

 row with a small Ivif definite int'rn-luimeral tubercle and 3-4 small granules. 



Venter clothed with brown pubescence, with a median white vitta, and 

 traces of lateral vittae.
