302 Appendix to the Proceedings 



at the apex, and the third and fifth or sixth enclose those 

 between them. Under side polished, shining, impunctate, except 

 a row of four or five large punctures on each segment of the 

 abdomen ; there are five segments, besides a side-piece in front 

 of them, but the first and second are soldered together, and the 

 separation between them is not to be seen except at the sides, so 

 that on a cursory view there only appear to be four segments; 

 tibise with spinous hairs on the exterior, strongest on the anterior 

 pair; posterior and middle tarsi longer than anterior. 



I have dedicated this species to my friend Mr. Adam White, 

 of the British Museum, to whose extensive information and kind 

 assistance I have been on many occasions much indebted. 



2. St. solidum, mihi. 



Prsecedenti valde affinis sed major, latior et convexior; tho- 

 race elytris vix angustiore, angulis posticis productis ; elytris 

 striato-punctatis, interstitiis impunctatis convexis. 



Long. 7~ lin., lat. 3 lin. . 



Very closely allied to the preceding species, but larger, broader, 

 and more convex ; the posterior margin of the eye is more en- 

 croached on by the chitinous substance of the head than in the 

 last; the polished space in the middle of the flat sides of the 

 antennae is rather broader, and is entirely smooth and without 

 punctures. Thorax more convex, broader, and less narrowed 

 behind than in the preceding species, scarcely narrower than the 

 elytra, bisinuate in front, and with the posterior angles project- 

 ing backwards ; there is a greater number of impressions in the 

 channel along the margin than in the last species ; prosternum 

 with several deep punctures arranged somewhat in a longitu- 

 dinal double row along its projecting part. Elytra punctate- 

 striate; interstices impunctate and convex, the punctures and 

 impressions on the sides deeper and more distinct than in the last 

 species ; the stria next to the suture also is nearer it, which makes 

 the rest of the interstices look wider ; the part of the elytra 

 beside the suture is more depressed than the rest. In other 

 respects the two species agree. 



Buderes, mihi (/3ov$ and Biprj), 



Caput parvum, quadratum, parum convexum, pone oculos sine 

 tumore, sed parte postica oculorum tecta. Labrum trans- 

 versum, antice quam postice latius, angulis anticis projicicn- 

 tibus margineque antico emarginato et ciliato. Mandibular
