30i) MAXDIBUI.ATA. COLEOl'TF.UA. 



As far as I am aware four specimens of this beautiful species have 

 hitherto been captured in England; they were taken by Dr. Leach 

 near Cheltenham ; one of which he gave to Mr. Kirby, who nevex 

 found the insect either in Suffolk or elsewhere, as assumed by Mr. 

 Curtis. 



Genus DXXIX. — Siagoxium, Kirhy. 



Antennae very long, pubescent^ filiform, the basal joint longest, stout, the 

 second slender, the remainder gradually increasing in size to the apex, 

 oblong, the terminal one obovate. Palpi filiform, maxillary longest, apical 

 joint cylindric ovate : labru?n bilobed : mandibles dissimilar in the sexes, in 

 the males furnished with a very long tooth within, in the females simple : 

 head triangular-orbiculate, as wide as the thorax, armed, in the males, with 

 a horn on each side before the eyes; unarmed in the females: eyes hemis- 

 pheric : thorax obcordate, dilated in fi-ont, finely margined : body linear, 

 depressed : elytra long : legs short ; femora simple : tibiw ciliated within, 

 and the two anterior pair denticulate without : tarsi five-jointed, the terminal 

 joint as long as the other four united. 



From the genera of this family, which have the anterior tibiae more 

 or less denticulated on their outer edge, the insects of the genus 

 Siagonium may be at once known by having the tarsi five-jointed; they 

 also differ by their depressed linear body, elongate pilose antennae ; 

 combined with a cornuted or tuberculated head, obcordate thorax, 

 &c. : they appear to reside beneath the bark of trees. 



Sp. 1. quadricorne. Piceum, nitidum, antennis, pedibus, elytris Uturd ohliqud 

 anoque rufis : mas, capite quadricorni. (Long. corp. 2 — 2^ lin.) 



Si. quadricorne. Kirby. — Curtis, \.pl. 23. Steph. Catal. 292. No. 3169. 



Depressed, pitchy, shining and glabrous; head dusky; tuberculated in the 

 female, horned in the male, the latter porrect, stout, incurved at the apex 

 and reddish-brown ; apex of mandibles resembling a second pair of curved 

 horns : thorax chestnut, punctulated, with a slender dorsal channel, and two 

 very obscure foveas at the base : elytra with four striae, two of them punc- 

 tured, the others slightly curved; disc with a rusty obliquely placed patch, 

 the outer angle dusky, abdomen dusky, with the extreme margins of the 

 segments and the apex reddish, the sides pilose : legs and antennae red- 

 First taken by Mr. Kirby (accidentally) near Barham in Suffolk, 



and afterwards by Dr. Leach : for many years these were the only 



known specimens ; about 10 years since a pair were taken by Mr. 



Denny in Norfolk, and thers in Kensington Gardens beneath the
