Synageles picata, Peckham. 



Synemosyna picata [lentz. 



I have one young male from New Haven, Conn., that appears to 

 be of this species. PI. XXI, fig-. 8. It is as large as adults sent me 

 from Wisconsin by Mr. Peckham, but not as distinctly marked. The 

 ceplialothorax has the two white spots in the middle, but is not 

 depressed at this part as in the adult. Fig. 3«. The coloring is 

 more uniform than in the Wisconsin specimens. The white marks 

 on the abdomen show indistinctly as do the markings of the legs. 

 The specimen is 3.5""" long. 



The adults of both sexes have a slight elevation around the pos- 

 terior eyes, and a distinct depression across the cephalothorax. Just 

 behind the eyes. Fig. 35. The front legs of the female are twice 

 as thick as the other legs, fig. 3c, and the front legs of the male 

 are still thicker, especially in the femur and tibia. Fig. 3f?. The 

 patulla and tibia are flattened in front, more in the male than in the 

 female. The front of these legs, and the front of the cephalothorax 

 of the male, are purple and iridescent in a bright light. In alcohol 

 they become dark brown. The abdomen has two white stripes 

 extending down the sides in the shallow depression across the front 

 third. The abdomen in front of the depression is rounded, and 

 sometimes swells in alcohol to an unnatural width. The hinder half 

 of the cephalothorax and front of the abdomen are lighter colored 

 than the parts before and behind.
