BY THE REV. T. BLACKBURN. 97 



The followiiifj characters in combiaation place this species in 

 Section iii., Group vi. of the genus (tabulated P.L.S.N.S.W., 

 1889, pp. 426-8) : labrum overtopping the clypeus and causing its 

 outline from a certain point of view to appear trilobed, antennae 

 9-jointed, claws furnished with a projection close to the apex, 

 almost perpendicular to the line of the claw. In that group it is 

 associated with II. borealis, Blackb., by the following characters 

 in combination : external margin of hind coxae evidently shorter 

 than the metasternum, antennae entirely of pallid colour ; middle 

 lobe of " trilobed outline " of clypeus widely rounded and not 

 much narrower than the lateral lobes, prothorax moderately closely 

 punctulate (intervals between the punctures somewhere about -^ 

 the length of the prothorax), joint 2 of hind tarsi evidently longer 

 than joint 1. From H. borealis it differs inter alia by the pro- 

 thorax being narrower in front, with more rounded hind angles, 

 and by the middle lobe of the " ti'ilobed outline " of the clypeus 

 being wider than in borealis and not more prominent than the 

 lateral lobes. The sides of the prothorax are somewhat strongly 

 rounded.

This species falls in the same group as the preceding, which it 



reseojbles somewhat closely in respect of colour and puncturation, 



differing from it, however, widely in respect of some important 



structural characters. Its labrum is considerably narrower and 



more elevated, .so that the "trilobed outline" of the head has 



quite a dift'erent appearance, the middle lobe being less than half
