Lophocarenum trilobatum. (Plate III, figures 1, la.) 

 Dicyphus trilobatus, Banks. Canadian Entomologist, 1800. 



One male only from the maple swamp at Clarendon Hills, about 

 the same size as L. montiferum, with, a hump as high as that species, 

 but differently shaped. The cephalothorax is not quite as wide as 

 long, and a little narrower in front. The e3 T es are grouped together 

 as in most species, the hinder middle pair a little farther apart than 

 they are from the lateral and the lateral pairs almost horizontal. 

 The hump is half as wide as the cephalothorax and nearly of the 

 same height. It is rounded behind and in front divided into three 

 lobes, the middle one extending forward nearly to the eyes. The 

 palpi are longer than the cephalothorax, the tibia a little shorter 

 than the patella, but elongated over the tarsus on the upper side, 

 so that it appears longer. This process of the tibia is divided into 

 two teeth, the outer one longer and larger than the inner. The 

 palpal organ has some resemblance to that of montiferum, with a 

 small tarsal hook and the tube curled once around the end. 



Lophocarenum minutum, new. (Plate III, figures 8, 8a, 8 b.) 



1 mm. long and light yellow brown. The cephalothorax is one- 

 fourth longer than wide and rounded in front. The head is only 

 slightly elevated, and the lateral grooves are behind the eyes, with 

 the pits showing from above through the skin one-third the length 

 of the cephalothorax from the front. The sternum is as broad as 

 long, extending backward between the fourth legs, where it is as 

 wide as one of the coxae. The palpi have the patella and tibia 

 both short, about as wide as long. The tibia is a little widened 

 toward the tarsus and has on the upper and outer side a short, 

 fine and slightly curved tooth. The tarsal hook is long and slender, 

 and in my specimens turns outward so that it shows from above. 

 The palpal organ is small and simple, and there is a short and 

 blunt black process that extends beyond the end of the tarsus. 

 The tarsus is slightly angular on the outer side. The female has 

 the head slightly lower, with the upper and lower middle eyes 

 closer together. The epigynum resembles that of several other 

 species of the genus having a distinct middle lobe, widened at the 

 end in front of which are two openings.

Lophocarenum rugosum, new. (Plate II, figures 3 to 3g.) 



2 mm. long. The cephalothorax is oval, widest across the middle 

 and highest behind the eyes. The surface is slightly roughened all
