224 INSECTS OP THE CAIRNS DISTRICT, NORTHERN QUEENSLAND, 



striate-punctate ; the interstices broad and rugose with numerous 

 longitudinal scratches. Under surface lightly villose. Club of 

 antennae yellow. 



Length, 4 lines. 



Hah. — Cairns. 



20. Onthophagus lobicollis. 



Black, very nitid, the head and thorax greenish-black. Head 

 finely and rugosely punctate, in front broadly rounded, the clypeal 

 suture raised, and a transverse ridge, triangularly emarginate in the 

 middle and triangularly raised and curved outwards, near the back 

 of the head. Thorax smooth, in front a large and prominent 

 tubercle, emarginate in the middle of its apex, which is bisinuate, 

 the sides jutting out into two strong pointed tubercles, and strongly 

 striated behind, with a deeply excavated space on each side. 

 The elytra quite smooth with fine striae rather thinly punctate, in 

 other respects resembling the previously described species. The 

 pygidium and under surface rather densely cinereo-villose. 



I have numerous specimens resembling this species in some 

 respects, though very difierent in others, which may be females. 

 In the absence of proof I cannot accept them as the females of 

 this species, and it would be still worse without proof to describe 

 them as distinct. 



Von Harold who has devoted much attention to the genus 

 Onthopliagtts, has I regret to say neutralised much of the good 

 work he has done, by his frequently forming new species out of 

 his unmatched females.

21. Onthophagus emarginatus. 



Black, the head and thorax bronzy black, nitid, the elytra 

 sub-opaque. Head sparingly punctate, the clypeus rounded, 

 except at the apex which is a little emarginate, on the back of the 

 head a transverse crescent-shaped ridge, the horns rather strong 

 and sub-acute. Thorax slightly retuse in front, the anterior
