the middle coxae. On the other hand, Walsh's species is described 

 as having the mesosternum and more or less of the mesopleurum red. 

 The description is based primarily on the female. The first female 

 mentioned, therefore, would be the logical choice for lectotype were 

 the specimens in existence. Unfortunately they were destroyed in 

 the Chicago fire in 1871. The first female mentioned is the one 

 reared from the gall of {Euryptychia saUgneana Clemens) =^;?*- 

 tlema scudderiana Clemens on goldenrod. In the National Museum 

 is a female, reared March 16, 1887, from this host, which agrees 

 almost perfectly with Walsh's description. It is recorded as Glypta 

 animosa Cresson in Insect Life as cited above. This specimen I 

 hereby designate the neotype of Glypta rufiscutellaHs Walsh (not 

 Cresson) and rename the species as above. 



Otherwise the neotype dift'ers from ruftscutellaris Cresson by 

 having the cheeks more strongly rounded, the flagellum stouter with 

 second joint distinctly less than twice as long as thick, the ovipositor 

 a little shorter, hardly as long as abdomen, and the upper lateral 

 margin of pronotum white throughout. 



Other specimens that I place under this species were reared by 

 Frank D. DeGant at Cleveland, Ohio, from the gall of Gnori- 

 moschema gallaesolidaginis Riley and, apparently by Riley at St. 

 Louis, from " stem of wild hemp." 



The extent of red on the thorax in both I'ufiscutellans Cresson and 

 caulicoJa varies greatly, specimens occurring in both species in which 

 the mesoscutum, mesopleura, mesosternum, metapleurum, metaster- 

 num, and sometimes even the scutellum are entirely black. In cauli- 

 cola the red first appears on the mesosternum and metasternum and 

 on the lateral lobes of the mesoscutum, while in ru-fiscuteUans it 

 appears first just in front of the coxae on the pleura and in the 

 notauli on the mesoscutum.

FeTimle. — Length 6.5 mm ; antennae 6.5 mm. Head strongly trans- 

 verse, subopaque granulate; temples not reaching nearly to outside 

 tangent of eyes, strongly convex ; occipital carina broadly interrupted 

 medially; diameter of an ocellus a little shorter than postocellar line 

 and little more than half ocell-ocular line; eyes slightly convergent 

 below; clypeus broad, in profile with apex prominent, with a fringe
