collis^ although their description is short and does not inchide the 

 essential characters used at present for separating the species of 

 this genus. In comi^aring this specimen with specimens of dentipes 

 Germar from the United States, I can not find any differences. 

 These authors ^^ give a figure of a species which they have identi- 

 fied as dentipes Germar, but it is certainly not the species described 

 by Germar from North America, and since Castelnau and Gory 

 apj)arently did not know the true dentipes, I am inclined to place 

 rotundicoUis as a synonym of dentipes Germar. There is a unique 

 specimen under the name rotundicoUis in the British Museum, but 

 the specimen has not been examined. 



CHRYSOBOTHRIS BELLA, new species 



Female. — Form rather broad and moderately convex, and shining ; 

 above bright bluish-green, and each elytron ornated with reddish- 

 purpureous markings, all of which are obsoletely separated from 

 the suture, and arranged as follows: One covering basal fourth, 

 arcuately rounded posteriorly, and enclosing the green basal depres- 

 sion and humerus; a rather broad transverse fascia just behind the 

 middle, the margins irregular and expanded both near the suture 

 and lateral margin; and a rather narrow crescent-shaped fascia at 

 apical third, feebly oblique, with the concavity toward the apex; 

 beneath green; tarsi cyaneous. 



Head flat, with the front triangular, and the sides obliquely nar- 

 rowed to apex; occiput narrowly and longitudinally carinate; front 

 broadly and irregularly impressed, the impression causing an obso- 

 lete transverse elevation near vertex, in front of which the impres- 

 sion is deeper, and extending longitudially on each side to the 

 antennal cavities; surface very coarsely and irregularly punctate, 

 and the front sparsely clothed with short inconspicuous hairs ; inter- 

 vals finely and densely granulose; eyes large, strongly convex, more 

 arcuately rounded at bottom than on top, and separated on the 

 occiput by about one-half the distance between the antennal cavi- 

 ties; epistoma broadly angularly emarginate in front, and the lobes 

 broadly rounded; antennae short, third joint as long as the follow- 

 ing four joints united. Pronotum strongly transverse, nearly two 

 times as wide as long, widest near apex, slightly narrower behind 

 than in front; sides rather strongly angulated near apex, slightly 

 sinuate at middle, then feebly arcuately rounded to posterior angles, 

 which are rather acute and closely applied to the elytra; anterior 

 margin feebly arcuately emarginate, with an obsolete median lobe; 

 base very strongly angularly emarginate on each side at the elytral 

 lobes, the median lobe broadly rounded, and truncate in front of
