The larvse are olive-brown with markings almost as in the adult, the 

 head is more strongly pointed and there are two dots between the 

 black spot and the margin and two more against the eyes. 



This species occurs only in low swampy places ; a few full-grown 

 larvae and an abundance of adults were found the middle of August on 

 a low swampy meadow where a species o^ /uncus abounded. 



Athysanus extrusus V. D. (Plate VI., Fig. i.) 



Short and stout, over one-fifth of an inch long and nearly half that 

 wide, head short, no longer than the pronotum, wings shorter than the 

 body in one form which does not fly, longer with the under wings 

 more fully developed in the other form which flies readily. 



Color: Brownish-\ ellow to dirty straw, usually with four irregular dark 

 marks on the head ; the males are somewhat smaller than the females and 

 have a pair of long strap-like styles extruded from the abdomen be- 

 hind. 



The larvae are stout, active forms, yellowish with reddish and fus- 

 cous markings on the head and four rows of white spots on the abdo- 

 men; the legs and body are sparsely clothed with long, stiff hairs. 



Life History: They are found only in shaded locations, occuring 

 most abundantly in a rich bottom-land pasture where the underbrush 

 had all been cleared out, leaving only the larger trees; here the larvae 

 were found January ist less than one-third grown ; the day was warm 

 and they were very active. They were again observed the first of 

 April. Spring had fairly opened up and they were a little larger than 

 when observed in the winter. They mostly moulted April 6th and 

 again April 14th. the first adults appearing about the first of May, 

 these being males; the females began to appear a week later, and by 

 the middle they had all issued. The adults were abundant from then 

 until into July. Frequent examinations showed that the eggs were 

 not deposited until late in June or on into July, from which the larvae 

 hatch late in the fall and passthe winter. 



Athysanus texanus n sp. 



Somewhat resembling colonm ornamentation, slightly narrower, pale 

 yellow with two black spots on anterior margin of vertex behind which 

 are two broad parallel red stripes extending back across pronotum and
