CERAMBYCID.E. 22T 



Pitchy-black ; beneath somewhat castaneous : thorax with the lateral margins 

 bearing three acute spines ; the anterior and posterior margins bordered with 

 ochraceous hairs : elytra rugose-punctate, with three very obsolete elevated 

 lines on each, the apex obsoletely mucronated: breast rather densely pu- 

 bescent. 



Extremely variable in size. 



Not uncommon occasionally in the lane behind Coombe-wood 

 leading from Kingston to Merton. " Cambridge." — C. C. Babing-

Family XLVIL— CERAMBYCID^, Kirbi/. 



Body elongate, convex, sometimes slightly depressed : antennae inserted on the 

 inner margin of the eyes, generally setaceous, never serrated ; frequently 

 much longer than the body, 11- sometimes 12-jointed. Labrum exserted, 

 transverse ; maxiUae with two membraneous processes : paJ-pi with the ter- 

 minal joint largest : labium somewhat heart-shaped: head exserted, nutant, 

 sometimes deeply inserted in the thorax : eyes lunate : thorax subcylindric or 

 suborbicular, truncate anteriorly and posteriorly, the lateral margins fre- 

 quently dentate : elytra rarely abbreviated : legs compressed : femora gene- 

 rally elongate: tibiw slender, mostly unarmed: fora elongate, spongy beneath, 

 the penultimate joint deeply bilobed. 



Thefamily of Cerambycidse is preeminently distinguished amongst 

 the coleopterous insects by the great length of the antennae, in some 

 of the species these organs exceeding the body more than five times 

 its length : in habit the various groups are similar ; all being found 

 in their larva state in decaying trees, or imder bark, but some few 

 appear to prefer sound wood, which they perforate longitudinally : 

 — the perfect insects, which vary extremely in size, are found in 

 the trunks of trees or on flowers, especially of the umbelliferous 

 kind, and in dead hedges. The indigenous genera may be thus 

 distinguished by the subjoined, mostly external, characters :
