manuscript names. It is to be hoped, however, that Prof. 

 Uhler's Monograph of the N. A. Capsidse, in which these 

 species will be fully described, will soon be published. 



1. SPECIES FOUND ON SHRUB PINE (Pinus virginiana) . 

 Phytocoris eximus Reut. Quite abundant from June to 

 August. 



Phytocoris mundus Uhl. MS. Less abundant, collected dur 

 ing June and July. 



Megaccelum grossum Uhl. Found during July, August and 

 September ; not very common. Prof. Uhler took it also on 

 Pine bushes in Maryland, Pennsylvania and Massachusetts 

 during the month of July. (Hut. Amer., iii, p. 71). 



Pilophorus amoenus Uhl. This ant-like Capsid can be found 

 in great numbers on the Pine from the middle of June to 

 August. Prof. Uhler has also recorded it on Pine in June and 

 July in Maryland. (Ent. Amer., iii, p. 30). 



Pilophorus crassipes Uhl. MS. Allied to the former, but 

 more robust, and darker in color ; quite common in July, 

 August and September. 



Pilophorus l&tus Uhl. Smaller, and easily recognized by 

 the form of the antennae, the second joint being abruptly en 

 larged at tip ; less abundant than the two preceding species. 



Melinna modesta Uhl. A widely distributed species com 

 mon upon Pine trees during the whole summer and autumn ; 

 I have taken the larva in May. 



2. SPECIES FOUND ON RED CEDAR (Juniperus mrginiana). 

 Psallus juniper i Uhl. MS. A small and very frail insect of 

 light gray color variegated with red. Appears in the middle of 

 June, but is not common. I have also found specimens at 

 Berkeley Springs, W. Va., late in August. 



Lygus repletus Uhl. MS. Has been found in large numbers 

 from middle of June to August. I also took it at Berkeley 

 Springs, W. Va. This pretty insect is quite hard to detect on 

 account of its green color matching exactly that of the leaves 

 of its food-plant, but when seen, it is easily captured, because, 

 contrary to the habits of other Capsids, it does not take wing 

 so readily. 



Dichrocytus elegans Uhl. MS. Less common than Lygtis reple 

 tus \ found during June and July. It is easier to be seen from its 

 dark -red color of the corium. The three species just mentioned 

 occur in my experience always in company. 



3. SPECIES FOUND ON WILLOW (Salix nigra). Orthotylus 

 alternatus Uhl. MS. Abounds on Willow during the month of 

 June, but is less frequently found in July ; after that it disap 

 pears entirely. 



Pilophorus confusus Kirschb. Not uncommon during July 

 and August. Prof. Uhler found it upon willow bushes in 

 September. (Ent. Amer., iii, p. 30).
