Genus Entylia Germar. 



The synonomy of this genus has long been in an unsatis- 

 factory condition. The older species have not been redescribed 

 and Walker's numerous species are but poorly characterized. 

 My material is too scant to allow of my working out our forms 

 fully. In the following notes I have taken as my starting 

 point Fairmaire's identification of sinuata Fabr. and bactriana 

 Germ. I find in my collection three evidently distinct species: 

 a smaller southern form with the face more pointed, smoother 

 and more evenly punctured, the outer margin distinctly sin- 

 uated close to the eye, the tylus more heavily clothed with hairs 

 and the dorsal margin of the pronotum uneven or eroded in 

 places. This I have identified as sinuata Fabr. (PI. i, fig. 2). 

 A second and larger southern species with a shorter and more 

 evenly rounded face and a very high and falcate anterior pro- 

 notal crest which leans forward over the face and is oblique on 

 its superior margin, I have determined as concisa Walker (PI. 

 1, fig. 1). Our common large northern form has a larger and 

 rougher face the edge of which is broadly but feebly sinuated 

 along the sides and the dorsal margin of the pronotum is more 

 even. This I identify as bactriana Germ. (PI. 1, figs. 3,4). In 

 all of these the dorsal notch is quite similar, with the prom- 

 inences lower and less angular in the males. 



I give at the end of this paper a list in which the synon- 

 omy of these three species is given as I believe it should stand. 

 It is hardly possible that reducta Walker should be raised to 

 specific rank although it seems to have a shorter face with the 

 margins more regularly arcuated and not so much sinuated as 

 in our other forms of bactriana. This synonomy follows very 

 closely that given by Butler. 



Genus Publilia Stal. 



This genus was founded by Stal for those species of Entylia 

 in which the dorsum is not raised in a distinct crest but is more 

 or less sinuated. In this character however the fwo genera 

 run together completely and I have been unable to find any 

 good natural character to separate them. But it certainly is 

 convenient to have a distinguishing name for these depressed 

 forms and I prefer for the present to retain this and certain
