smallest of uur comiuou blister beetles. The color may be either light gra.\- 

 or yellowish, with scattered naked spots of the black liackground. The black 

 spots vary both in size and location, being barely dis- 

 cernible on some beetles and at least 0.3 mm. in di- 

 ameter on others. ,-^-^ S>. 



Egg. ^ ■^^ ■ -^-^ 



The egg of this species resembles that of ^Unio- 

 basis immacvlata, but is smaller. 



liARVA. 



Triungulin (fig. 13). — Length, about l.l^.j nun.: 

 width, about 0.4 mm. ; widest in front of middle of 

 head just behind eyes, from which point the head 

 tapers posteriorly for the last half or more of its 

 length. In this respect it agrees with triungulins of 

 Epicauta pcnnsylvanica and E'. Icmniscatct; but dif- 

 fers from Riley's figure of E. rittata.* The head of 

 the latter is parallel-sided, resemblijag Macrohasis 

 immaculata, but differing in having a very short pos- 

 terior portion or neck and in having the eyes located abuut the middle of 

 the length of the head. In all triungulins examined by the writer the eyes 

 are located nuich nearer the anterior ptn-tion of 

 the head. 



In other respects the triungulin of this species re- 

 sembles that of Macrobasis immaculata (p. S). 



Act ire larm\ — Neither the growing stages nor the 



third larva were recognized so they could be described. 



Coarctate larva. — The ^\Titer's records sliow one 



coarctate larva that measured 9 mm. long by 4 mm. 



wide which yielded an adult of this species. 



Pupa. 



The pupa of this species was not described for lack 

 „ , , „ . . . of authentic material. It is similar in color and ap-

Adit.t. 



Length of adult Epicauta cincrca (fig. 14), from 8 to 17 mm.; width, 1.75 to 

 4 nun. ; shape slender, with sides of elytra almost parallel ; color, bluish to 

 light or yellowish gray. 



Egg a XI) Active Lauva. 



Neither the egg nor any of (ho active larval .stages of tliis species were secured 

 for descriptive purposes. 



'Triungulins of this spocios were kindly furnishod by Mr. Thos. II. .Tones of the lUireaii 

 of Entoiuoloixy.
