Seventh antennal joint at apex of nearly the same width as the nintli 

 at apex, club very much produced withm, elytra black. 



Elytral intervals with very obsolete punctures and irregular elon- 

 gate impressions sanguinicoUis Chev. 



Elytral intervals with a very fine series of small punctures, varying 

 in strength Iceta Lee. 



I have not been able to secure specimens of /econtei znd. collaris 

 and the characters used for separation are taken from the descriptions. 

 The two last species seem to be very close, sanguinicoUis, which is said 

 to occur in Texas, is not known to me and I have used the characters 

 given by Mr. Gorham to differentiate the two species. Languria 

 tcBciata Lee. is somewhat intermediate between \.\i& g^txi^xz. Dasydactylus 

 and Languria, the anterior legs in the males are similar to those of Dasy- 

 dactylus ; the femora and tibiae asperate beneath in the males is one 

 of the characters used in defining that genus. The last mentioned 

 character seems to have escaped the observation of Crotch and others. 



Languria trifasciata Say is in my opinion entitled to specific rank ; 

 it has always the apices of elytra more pointed than angustata, the 

 markings and the intermediate red antennal joints and the red meta- 

 sternum seem to be also quite constant. Specimens of angustata are 

 occasionally found with the red at sides of elytra extending nearly 

 to suture, but. the color is never clear red, the metasternum and the 

 intermediate antennal joints always invariably black. 



Acropteroxys gracilis Newman. 



Specimens occurred at Brownsville with the typical form with the 

 thorax entirely red or only a black basal spot approaching Dr. Horn's 

 divisa. 



Dasydactylus cnici, new species. 



Elongate metallic green, underside reddish with metallic tint. Head sparsely 

 punctured, antennoe concolorus except the last four joints which are black, club five- 

 jointed. Thorax finely punctate, longer than wide, slightly arcuate at sides, feebly 

 sinuate before basal angles, which are rectangular. Elytra gradually narrowing to 

 apex, apices rounded and dentate ; striae not impressed, punctate, intervals smooth 

 with a row of fine punctures. Underside reddish with metallic tint, very finely and 

 sparsely punctate, last abdominal segment darker and a little closer punctured at 

 sides. Femora, tibiae and tarsi metallic green. Length, 6-IO mm.

 Museum in Washington. Dasydactylus differs from Languria and 

 allied genera in having the apices of elytra serrate, the males have the
