- Above black with the apex of the head, basal line of the 

 pronotum, two oval spots above this, the lateral margins 

 and tip pale; pectus and abdomen in part black, 



5, binotata Godg. 



4. Pale ; pectus, basal margins of the head and pronotum, and 

 median dorsal line expanded posteriorly, black, 



3, illinoiensis Godg. 



Black markings much more extended, the pronotum usually 



entirely black except at tip ; in pale specimens the black 



on the dorsum is gathered anteriorly and does not form 



a dorsal line widened before the apex, 2, calva Say. 



1. Micrutalis dorsal is Fitch. 



Size and appearance of Acntalis but with the elytral ner- 

 vures indistinct and with but four apical areoles. This insect 

 is not uncommon in the northern states and Canada upon wild 

 clematis. 



2. Micrutalis calva Say. 



Redescribed as Smilia flavipennis by Germar. This species 

 is widely distributed from southern New York to Florida and 

 west to the Rocky Mts. It shows great variation in the extent 

 of its black markings. I have seen specimens entirely pale 

 above with the pectus and femora slightly invaded with black. 

 Generally the pronotum excepting its tip and humeral angles, 

 the base of the head, all the pectus and the femora are deep 

 black. 



3. Micrutalis illinoiensis Goding. 



I believe this is a mere color variety of calva. I took two 

 examples at Milan, Ohio, that have the black dorsal line and 

 subapical spot as described by Dr. Goding and otherwise agree 

 with his description in every particular. 



4. Micrutalis occidentalis Goding. 



This is a pale species marked much as in illinoiensis but 

 the dark markings are paler and more diffuse. Some speci- 

 mens are entirely pale with a ferruginous line on the base of 

 the vertex and a sinuated subapical one on the anterior margin 

 of the pronotum. The Cornell University collection possesses 

 three examples taken at Riverside, California, in June. This
