shaped, fuscous. Pronotum about twice as long as the vertex, both 

 the anterior and posterior margins emarginate, a small depression 

 each side of median carina on disc. Scutellum with a median carina, 

 the lateral ones obsolete or with only a trace. Elytra large, long, 

 coriaceous, obliquely truncated at apex, the outer apical angle rounded, 

 piceous in color, the costa with grayish spots and this together with 

 the gray cross-veins give the insect a speckled appearance; veins 

 raised. Wings hyaline, venation fuscous, basal third clouded with 

 fuscous, with blue basal spots. Abdomen robust, black beneath, 

 sanguineous dorsally, base marked with black, with six round black 

 spots on each side of median ridge arranged in two rows, and in ad- 

 dition a few minute black dots; anal appendage clothed with short 

 white waxy secretion. Legs black, somewhat foliaceous, the first 

 and second pairs banded with white, the third pair with five lateral 

 spines on outer edge, bases marked with grayish spots. 



Length of body 9-12 mm.; length to tip of elytra 13-17 mm.; hum- 

 eral width 4.5-6 mm.

THE SUBFAMILY DICTYOPHORINAE (SPIN.) 

 Spinola, Ann. Soc. Ent. Fr., viii, pp. 202, 183, 1839. 



This subfamily is especially well represented in the 

 New World, seven genera being known from the United 

 States alone. Only three of these, Dictyophora, Scolops 

 and Phylloscelis, are known to occur, however, in the 

 eastern half of the United States. 



Members of these three genera at least are all grass- 

 feeding forms and occur rather abundantly, particularly 

 in low, damp meadows. They are among our most gro- 

 tesque and bizarre insects and arouse interest whenever 

 observed. 



The anal area of the elytra is rarely reticulated and 

 the clypeus is without lateral carinae; the veins of the 

 clavus do not attain the apex but are united with the com- 

 missural margin before the apex; frons without an ocellus 

 at its apex. 



Key to the genera 



Vertex triangularly produced; elytra greenish hyaline, the apical 



area more or less reticulate, Dictyophora Germ.
