10 MANDIBULATA. COLEOrTERA. 



Not common : taken occasionally in London, and I once caught 

 a specimen flyin<^ in a garden at Hertford : I have also received 

 specimens from Norfolk, captured, I believe, in Norwich. " Swaif- 

 ham Bulbeck, once taken." — Rev. L. Jenyns. 



GENUS CCCCXXVII.— Uloma, Megerh. 



^n/en7i(F slightly thickened towards the apex, 11-jointed, the basal joint robust, 

 elongate, second short, subglobose, third elongate, fourth scarcely shorter 

 than the third, two following transverse ; seventh and three followhig semi- 

 globose, the apical one globose. Palpi, with the terminal joint, incrassate, 

 of the maxillary compressed, obtrigonate : labium quadrate-cordate : man- 

 dibles, in the males, porrect, large, with the apex curved, acute, resembling 

 horns : Iwad suborbicular ; clypeus in the males tuberculate : thorax trans- 

 verse-quadrate : body elongate, somewhat depressed : wings ample : legs 

 moderate ; J'e7?to;-a rather stoutest in the male; iibice slender, all similar, 

 slightly thickening at the apex ; tarsi short, simple, heteromerous. 



The singularly curved and porrected mandibles of the males of 

 this genus sufficiently distinguish the insects of that sex from the 

 allied genera in this family, and both sexes may be known by the 

 dissimilarity in the proportions of the articulations of the antennae, 

 as well as by the similarity of all the tibiae, exclusively of other 

 characters.
