the muscular impressions on the scuta are distinct ; the lcg;s arc short with tlic claws 

 C(jual. 'Ihe \dr\ iv of A. spinipes, apricaria, Jajniliarift, iiiid patricia diiler from this 

 larva chiefly in the formation of the clypeus and head ; that of A. aprkarla is wiiite, 

 with the head pale yellow, with the margin of the clypeus and mandibles ferruginous, 

 and the dorsal abdominal and thoracic scuta yellowish-white. 



Accordin<r to Ziinmoruiann the eggs arc deposited under stones or at a small depth 

 underground ; the larvje change their skiu once, and attain, previous to becoming 

 pu])te, twice the length of the iiuago ; in general form they closely resemble those of 

 Zabriis and Pcecilus ; they remain about six or eight weeks as larvae, and half that 

 time as pupae. ( Vide West wood. Class, i., pi 71.) 



In ImViits many of the Amarae resemble Zabrus, notably perhaps those 

 tliat belong to the sub-genus Ciirtonotun (some of -which rather closely 

 reseml)]e that genus also in size and appearance). They are partly 

 vegetable feeders and partly carnivorous ; they are found at times de- 

 vouring the seeds of plants in the ripe flower-heads, but they also 

 ;i])pear to attack the stems, pith, and roots of grtisses and various other 

 plants, as well as being voracious devoufers of the larvae of other insects. 



For the sake of' convenience the genus may be divided into the 

 following sub-genera, which, however, are of somewhat unequal value : — 



I. Prothorax narrowed feebly (sometimes hardly percep- 

 tibly) towards base ; prosterual process margined at 

 apex ; posterior tibia; in male deusely pubescent on 



inner side Beadttijs, Staph. 



II. Prothorax cordiform, sides strongly contracted at 

 base ; prosternal process not margined at apex ; pos- 

 terior tibiue glabrous in both sexes CuETONOTirs, Steph. 



III. Prothorax subquadnite, sides only slightly contracted 

 in front, and straight or almost straight behind ; pos- 

 terior tibia; glabrous in both sexes ; upper surface as a 



rule not, or not strongly metallic. 



L Upper side strongly convex ; anterior tarsi of male 

 with the three dilated joints broadly cordiform ; apex 

 of pi'osternal process bearing several setre .... Peecosia, Zimm. 



ii. Upper side feebly convex ; anterior tarsi of male with 

 the three dilated joints more or less broadly trian- 

 gular ; apex of prosternal process bearing not more 

 than two seta; or quite glabrous Celia, Zimm. 



IV. Prothorax trapezoidah, very strongly contracted in 

 front, widest at base ; posterior tibia; of male densely 



pubescent on their inner side. 



i. Inner terminal spur at apex of anterior tibia; simple . AmaEA, /. sp, 



ii. Inner terminal spur at apex of anterior tibia; tri- 

 cuspid Tki^na, Leconte. 



(Suli-Gcn. Bradytus, Stephens.) 



I. Colour fulvous, with slight metallic rertection ; thorax 



with sides strongly rounded in front A. F0LVA, De. O. 



II. Colour dark (pitchy or bronze) ; thorax with sides not 



strongly rounded in front. 

 i. Form oblong, narrower ; side border of thorax very 



plain A. apricaeia, Pai/k, 



ii. Form oval, broader ; side border of thorax very 



narrow A. consulaeis, Diifl.
