Tricliopteryx.'] CLAVICORNIA. 127 



Two specimens taken at Weston, Oxfordshire, by Mr. Matthews, iu moss. 



T. variolosa, Muls. (Bceocrara Utforalls, Thorns.). Suboval, shining, 

 convex, nigro-castaneous, or nearly black, sparingly clothed with stout 

 silvery hairs, not tuberculate, but with the whole surface impressed with 

 large punctures, variolose ; head large, elongate in front, eyes prominent, 

 antennae long and rather slender, pitchy-testaceous ; thorax short, trans- 

 verse, with sides strongly margined and rounded in front and behind, 

 posterior angles acute, not produced ; scutellum large, deeply punctured ; 

 elytra rather short, dilated behind, with the sides rounded and strongly 

 margined, apices broad, almost straight ; legs long, clear yellow, femora 

 pitchy ; under-side castaneous, mouth and coxae yellow. L. | mm. 



In moss, dung, &c. ; rare; the first British specimen was taken by Mr. Matthews 

 near Gumley, Leicestershire, February, 7th, 1862 ; subsequently Mr. Matthews found 

 another in the same locxlity ; it has also occurred at Esher, near London ; Mr. Wollas- 

 ton has taken it on Dartmoor, in Devonshire, and Dr. Sharp iu the New Forest 

 and in Scotland, in which country he records it as rare in sheep's dung, Tay district 

 (Rannoch). 



Thomson separates this species on the ground of the sculpture and 

 strongly margined thorax as a new genus Boeocrara ; it is true that it 

 presents the only instance of true punctuation in the genus, but the 

 margined thorax is found in other species, and the mouth parts, &c., 

 appear to be identical ; I have therefore followed Mr. Matthews in 

 keeping it under Tricliopteryx. 



SMICRUS, Matthews. 



This genus contains one European species, which is distinguished 

 from JHficroptilium, which has been included under it, by having the 

 thorax plainly constricted behind, and also by the long ligula, and 

 narrowly laminate posterior coxae ; it is extremely rare in Europe, but 

 rather common in North and South America ; it is found in dung-heaps, 

 and also in the sandy banks of streams. 



S. filicornis, Matth. (Micrus, Matth.). Oblong, subparallel, con- 

 vex, dull black, very thickly clothed Avith short yellow hairs ; head 

 large, broad, minutely and closely tuberculate, antennae very long and 

 slender, yellow ; thorax transverse, with sides rounded in front, and 

 constricted at base, very closely and minutely tuberculate, posterior 

 margin almost straight, angles acute ; scutellum large ; elytra rather 

 long, with sides almost parallel, very closely and deeply asperate ; abdo- 

 men rather long, with five segments exserted ; legs long, robust, clear 

 yellow ; under-side pitchy-black, with mouth, coxae, and apex of mcta- 

 sternum clear yellow, apical segment in male broadly and deeply emar- 

 ginate, with a long process in middle, armed on each side with an 

 elongate sharp spine. L. f-lf mm. 



Very rare ; once found by Mr. Matthews in numbers on the banks of the Rye,
