390 J. H. Emerton, 



attached. Fig. 8d. The end of the tibia is obHquely truncated and 

 the outer corner has a small recurved point. Fig. 8 c. The tarsus 

 is round and the palpal organ small and simple. The palpus re- 

 sembles that of Dicymbiiim gracilipes of Europe. 



One male only under leaves at Three Mile Island, Lake Winnipe- 

 saukee, Oct. 10, 1909. 



Histagonia nasutus, new. 



Male 2 mm. long. The front of the head extends forward beyond 

 the mandibles and upward as high as the front eyes, covered on 

 the highest part with short hairs directed upward and backward. 

 The head is elevated and the eyes all turned upward. PI. I, figs. 

 9, 9a. Seen from above the cephalothorax appears pointed in front 

 as in H. palustris. The abdomen is oval and the whole body dull 

 gra}^ without markings. The male palpi resemble those of H. palu- 

 stris but the tibia is more simple and the parts shorter and less 

 pointed without the distinct wedge-shape when seen from above in 

 palustris. The palpal organ is much as in palustris with the tube 

 shorter and the support longer and more pointed. 



One male only with palustris in dust and leaves washed up on 

 the shore at Three Mile Island, Lake Winnipesaukee, N. H. 



Lophocarenum bilobatum. 



Dicyphus bilobatus. Banks. Canadian Entomologist, 1896. 



In size and color this resembles L. decemoculatum. The cephalo- 

 thorax and legs are bright orange and the abdomen bluish black. 

 The cephalothorax is nearly as wide as long, rounded in front and 

 without the projection over the mandibles which is so distinct in 

 deceuioculatum. The hump is divided into two distinct lobes, each 

 oval, and about twice as long as wide. PL II, fig. 1. The holes 

 in the head are close behind and a little higher than the upper 

 lateral eyes, fig. 1 a, appearing from in front like an additional pair 

 of eyes as in decemoculatum. Behind the two lobes and around 

 their outer sides the cephalothorax is slightly elevated. The male 

 palpi are more slender and the palpal organs smaller than in decem- 

 oculatum. The tibia has on the upper and inner side a slender, 

 slightly curved hook, extending along the edge of the tarsus more 

 than half its length. Fig. 1. The palpal organ is simple, the tube 

 and a soft conductor arranged as in decemoculatum and Jlorens, but 

 smaller and more slender. Fig. 1 b.

 meadow, May 15, 1910.
