The rather numerous species range from North America to 

 Japan, and occur also in Indo-Malay region, Africa and Australia. 



Tmesiphorus Kingii, Macleay. 



Trans. Ent. Soc. KS.W. 1873, ii. p. 101. 



This is a fine insect; the head and prothorax are densely rugoso- 

 punctate; the elytra are much less punctate, more especially in 

 the depressions which are nearly smooth, the abdomen is more 

 evenly punctate than the elytra; in the £ the 9th antennal joint is 

 rather obconjcal, 10th more cylindrical, but emarginate beneath, 

 11th large, subglobose. and somewhat gibbose beneath in the 

 middle; in the Q 9th and 10th are similar to each other and more 

 regularly subovate, 11th is a little larger and ovate.

Tmesiphorus Macleayi, King. 



Trans. Ent. Hoc. KS.W. i. 1863, p. 40; 1864, p. 102: Sintecte* 

 carinatus ('?) Westw., Trans. Ent. Soc. Lond. 1870, p. 130; Thes. 

 Ent Oxon. PI 4, f. 10. 



I do not know this species, which, according to Macleay, is 

 lighter in colour and not so rough nor so strongly sculptured as 

 Kingii. 



This species is probably identical with Sintectes carinatus, 

 Westw.; a very important point of concordance in the descrip- 

 tions of the two entomologists is the relative proportions of the 

 9th and 10th joints of the antenna?, 10th being smaller than 9th. 

 There is, however, a difference in the colouration which is described: 

 as darker by Westwood than by King, but in these insects the 

 colouration is a mere cpiestion of maturity. At any rate Sintectes 

 carinatus, Westw., is specifically different from Tmesiphorus 

 Macleayi, King; according to the figure of S. carinatus given by 

 Westwood in the Thes. Ent. Oxon. (PI. 4, fig. 10a) of the maxillary 

 palpus, the last joint of this organ being more dilated and more 

 rounded outwards than is the case in Macleayi, King. 



It may still prove possible that S. carinatus, AVestw., is a 

 distinct species, but it is rather strange that it has never been
