applied to prothorax, shoulders oblique; with rows of large distant 

 punctures; suture nowhere carinated; second and third (and to a 

 less extent the fourth and fifth) interstices flattened on their basal 

 third; elsewhere, and all the others, more or less acutely carinated. 

 Metasternwn concave in middle, strongly raised and densely punc- 

 tate on each side of middle, then with rather large sparse punctures; 

 each side piece with a row of very small punctures. Abdomen with 

 punctures varying from rather large to very small ; third and fourth 

 segments each with a row of feeble punctures across middle, but 

 with a few more at sides; basal segment concave in middle in male, 

 convex in female. Front femora feebly, middle moderately, hind 

 pair rather strongly dentate. Length 4-5 mill.

In the table previously given by me this species should be placed 

 next to porosm, from which it differs in being wider, the elytral 

 interstices with less conspicuous punctures, and less flattened at 

 the base, the prothorax with smaller and less rounded punctures, 

 much smaller femoral teeth, mesosternum more depressed, rostrum 

 longer, &c. The clothing of the metasternam is faintly suggestive 

 of pectoralis, but the two species have little else in common. The 

 part of the rostrum in front of the antennas is usually paler than 

 the part behind them. 



394. Melanterius strahonus Lea. 



There are specimens in the Belgian Museum from Port Denison 

 and Rockhampton, which I cannot structurally distinguish from 

 the type of this species (from N. W. Australia), but they differ in 

 being slightly smaller and somewhat diluted with red. 



395. Melanterius corrosus Boisdv. fCryjUorliynchusJ. 



The type of this species has been sent to me for examination. It 

 is a Melanterius, and very close in general appearance to adipatns. 

 From that species it differs in being somewhat larger, in having the 

 prothorax distinctly longer and with more numerous and rather 

 smaller punctures; the punctures on the head are more noticeable 

 than in adipatns, but the elytral sculpture is almost identical. The 

 abdomen of the type is missing, but there is a second specimen in 

 the museum from Sydney, and I have three others from Gisborne ; 

 and these have rather coarse punctures on the apical half of the 

 apical segment, the two basal segments have large, clearly define^l 

 punctures. 



From porosus it differs in being somewhat smaller, the elytra less
