THE CANADIAN ENTOMOLOGIST, 63 



outer side, twice as long as wide, and appressed to the tarsus so as to be 

 hardly visible except in side view ; palpal organ very large, with the 

 lower part full and extended over the base of the tibia j on the outer side 

 near tip is a crescent-shaped yellowish mark ; the bulb is small and on 

 one side, and is tipped with a minute spine-like tube. 



One (J, Mt. Washington, N. H. [Mrs. Annie T. Siosson]. A very 

 distinct litile species, and doubtless peculiar to mountains. 



Dismodiscus alpimis, n. sp. 



Length, 2 mm. Cephalothorax pale yellowish, blackish around eyes, 

 sternum infuscated, abdomen dark gray, legs almost white. Structure 

 somewhat like Loph. decem-oadatuin, Em., with a large lobe on the 

 clypeus as in that species, but the lobe on the head is higher, narrower, 

 rounded above, not bilobed, clothed with short hairs on top and in front, 

 and rises suddenly from the surface of the cephalothorax in front and 

 behind ; the P. M. E. are on the cephalothorax at its base, and not 

 on the lobe ; the holes are in a large groove on each side. The posterior 

 row of eyes is straight, equal in size, the P. M. E. fully as far from each 

 other as from the S. E.; the anterior row is slightly recurved, the A. M. E. 

 very small and close together. Sternum but little longer than broad, 

 truncate at base, pointed behind, sides rounded. Legs slender, a spine 

 above on patella and two on tibia iv., tarsus i. plainly shorter than the 

 metatarsus. The tibia of the $ palpus has above two short spines and 

 two projections at its tip, the outer one the broader and pale, the inner 

 one more pointed and reddish; the palpus is barrel-shaped, the tube 

 going once around the tip as in Diplostyla; there is a large curved hook 

 at base. 



One $, Mt. Washington [Mrs. A. T. Siosson]. Although this 

 species dots not strictly agree with Simon's description of the genus 

 Dismodiscus, I believe it should go here, as also Loph. decem-oculatum, 

 Em. The best character for the genus to me is the clypeal lobe. 



Dicyphus, Menge, which Simon unites to Gonatium, I would agree 

 with Kulezynski in keeping as a separate genus, and closely related to 

 Dismodiscus. The head of the $ has a lobe above which does not 

 bear the P. M. E.; there is no clypeal lobe. I have seen two species 

 from the United States, the first of which has much affinity with the type 

 of the genus, D. biiuberailatus. 



Dicyphus bilobatJis, n. sp. 



Length, $ , 2 mm. Cephalothorax orange, a little black around the
