of elytra yellowish, upper surface coarsely and closely punctate. Elytra 

 with four more or less well-marked costae. The food-plant of this beetle 

 is still unknown to me, for, while I have collected a great many speci- 

 mens, they were always found under logs or stones. 



Cerotoma, Chevr. 



Represented by C trifurcata, Forst. {caminea, 

 Fabr.), resembling somewhat the common Diabrotica 

 i2-pu7ictata in form, but shorter. Head and under side 

 of body black, upper surface of thorax and elytra 

 yellowish or occasionally red. Elytra marked with 

 black, as shown in fig. 4, this pattern being often re- 

 duced or added to by the greater or less extension of 

 the yellow. Length, .14-. 20 inch. Mr. Chittenden records the bush- 

 clover, Lespedeza, as a food plant, and remarks that legumes form the 

 chief food of the species. My own captures have been, for the most 

 part, made by overturning boards and chips in patches of meadow land 

 during the middle of spring. 



A GENERIC REVISION OF THE HYPOGYMNID^: 



(LIPARIDyE). 



BY HARRISON G. DYAR, NEW YORK. 



Before the generic names of our moths can become permanent, it is 

 necessary that all the described genera should be compared, but specially 

 the older genera of Europe. To make a beginning in this matter, I have 

 drawn up the following synoptic table of the Hypogymnidas, based on 

 the characters used in Hampson's Moths of India, adding thereto the 

 species found in Europe and in North America. The types of the genera 

 are recognized as determined by Kirby. 



Probably but few, if any, changes will be necessary from this list, as 

 the African and South American species for the most part belong to other 

 genera, or else have later dates than the generic names here defined. 



I exclude two genera given by Hampson, viz. : Retarda and 

 Thiacidas. The latter seems to me to be a Noctuid, perhaps one of the 

 Apatelidse, while the former has the venation of the Tineides and is 

 without frenulum ; it probably represents a new family type. 



In the Tentamen, Hiibner gives the three plural terms, Hypogymnae, 

 Leucomae, and Dasychiras, all referring to this family. As these appear 

 to be the first plural terms, one of them must stand for the family. The
