 it is at once distiniruislied by the lack of thoracic vittie. 



885a. Sphenophorus callosus sublaevis Chitt. — Dr. Chittenden (Ms.) 

 states: ''This species (siiblcrz'is) is absolutely not a variety of collosus. 

 It is more nearly related to destructor Chittn., from which it is sepa- 

 rated by its much more irre.cjular elytral surface. I freely admit that 

 the> distinction (between destructor and siibUcvis) is not very strong, 

 but I find no specimens which intergrade sufficiently to separate 

 sublcrvis as a race of the other." The Vigo County, Ind., specimen 

 recorded (p. 568) he places as destructor, the Lake County ones as 

 subl<cvis. He al-so adds: " S. destructor is one of the variable species 

 and I have found it on occasions in the same lot with callosus but 

 have no trouble in separating it from that species by the characters of 

 the thorax alone, the middle vitta being irregular, elongate fusiform. 

 with an irregular interrupted, shining black elevated line extending 

 from apex to near base. This finely elevated line is never found in 

 callosus." Basing conclusions on small series, Dr. Chittenden is justi- 

 fied in his statement, but if a collection from the entire countrv were 

 brought together, it would perhaps show that destructor, callosus and 

 sublccvis would merge, sublccz'is being the northern race of the other 

 two, the typical form being callosus. All three are also closely related 

 to S. zecv Walsh. 



S89a. Calandra oryzse zea-mais Mots. — Of this form Dr. Chitten- 

 den (Ms.) says: "This is an absolute synonym of oryza. Years of 

 experience in rearing this insect has convinced me that it is not 

 divisible into distinct species or even races. The size is dependent 

 upon the food supply. Large specimens are usually bred from com- 

 paratively soft corn where they have an abundance of food; small 

 ones from small grains of hard rice."
