are larger than normal, but in this respect are not at all comparabj^e with the large 

 deep depressions of M. inultipimctatus and M. sobrinus. One sp/^cimen.

Readily distinguished from JM. sobrinni by its smaller size, more shining elytra, 

 and the fact that the elytra foveoles are ip.creased in number by additions placed laterally. 

 It is apparently e.xtremely rare, only four examples being known.

(21) Mecyclot/i07-ax interntptiis, sp. nov. 



Elongatus, nigricans, antennarum basi, palpis pedibusque testaceis, elytris fuscis, 

 margine late rufescente ; prothorace magno, transverso, basin versus sat angustato, 

 angulis posterioribus denticulato-rectis ; elytris profunde striatis, ultra medium striis tertia 

 et quarta interruptis, interstitiis tertio et quinto propter hoc conjunctis. Long. 5^ mm. 



A very peculiar form, exhibiting as it were the earliest form of the peculiarity of 

 sculpture that is developed in such a remarkable manner by T. pcrkinsi and T. laticollis. 

 The antennae are rather long, dusky, the basal joint yellow, the following two dusky 

 reddish. The thorax is broad, not greatly narrower than the elytra, blackish, with the 

 sides narrowly yellow, and the base somewhat yellowish ; the hind-angles would be 

 obtuse, were it not that the angle itself is a little prominent and sharp ; the anterior 

 depression is very deep, and so is the median channel, but it is not continued to the 

 base. The elytra are deeply striate, all the eight striae being entire, they are not 

 punctate, though their margins are slightly waved ; the anterior foveole on the third 

 interstice is very definite, the posterior foveole is followed by an irregularity of sculpture, 

 an isthmus connecting the third and fourth striae ; there may be one or two other similar 

 irregularities of sculpture present ; the colour is blackish about the suture, with the outer 

 margin broadly reddish.

Van dubiiis van nov. Formae typicae affinis sed minor, supra aenescens, elytris 

 minus profunde striatis, striis tertia quartaque haud interruptis, margine externo 

 angustissime flavo. 



The.se three varieties were not found in company. The type form was found in 

 May 1896, number 680; the van integer in October 1896, the van dubitis in May 1896, 

 but as numbers 622 and 623.
