NATURAL SCIENCES OF PHILADELPHIA. 79 



Paler varieties have the dorsal mark less developed, and are 

 described by Boheman as C. traheata and C. lucidula. 



4. C. purpurata, Boh. Mon. iii. p. 300. 



Above brownish-red, with a lateral triangular hyaline patch, 

 body beneath black, antennae and legs pale. L. .23. Kansas, 

 Pennsylvania. 



5. C. Lecontii, sp. nov. 



Differs from the others by its more oval, depressed form, recall- 

 ing that of Cassida; the antennae are however long, the last two 

 joints black ; body beneath pale ; thorax with an M-like mark at 

 the base ; elytra with the disk black, variegated with fulvous, 

 humeral angles black at the point. L. .24. Arizona (Leconte). 



6. C. clavata (Fabr.) Boh. Mon. iii. p. 391. 



Pale testaceous, elytra brown, tuberculate, gibbous, margin 

 with a large oblong hyaline spot in the middle, and a small sub- 

 apical one; antennae with the last joint dark. L. .30. Southern 

 States, 



7. C. bisignata, Boh. Mon. iii. p. 119. 



Ovate, rufo-ferruginous, body beneath and last four joints of 

 antennas black; elytra cfeeply punctate striate, disk with a round 

 black dot. L. .29. " America borealis." This species is unknown 

 to me. 



8. C. plicata, Boh. Mon. iii. p. 493. 



Easily distinguished by the claws pectinate at the base ; body 

 beneath pale, last joint of antennae black, elytra with the disk 

 black, and a well-marked foveole on each. L. .28. North Amer- 

 ica. I have not seen this. 



[A large species from Mexico and Texas has the elytra acutely 

 gibbous, and is probably described in Bolieman ; it has been re- 

 ceived from Europe with the MS. name lucida.'] 



HISPIDES. 



The species of this group are but few in number (19), but their 

 synonj^my is somewhat confused, and their descriptions do not 

 exist in any accessible works. I have therefore made the follow- 

 ing brief diagnoses to enable the student to name his species, 

 leaving full descriptions for a time when the whole family of 

 Chry&omelidae shall undergo revision.
