200 [September, 



This new genus and species to niir list was discovered by Mr. 

 Claude Morley under liawthorn bark in Richmond Park, on March 

 2nd, 1898. 



It may be known from Xylocoris gencrically by the sliorter 1st and longer 2nd 

 joints of its rostrum, by the long 4th joint of tlie antennae, which is much longer 

 than the very short 3rd joint, by the eyes being further from the anterior margin 

 of the pronotum, and by its abbreviated elytra. 



It is an elongate insert, flat, very shining and black, with the exception of the 

 dull, slightly paler elytra ; eyes about equidistant in position between the apex of 

 the face and the margin of the pronotum ; 2nd joint of the antennae pale and 

 slightly thickened, dusky at the apex ; pronotum narrow, apical constriction slight, 

 lateral margins carinated, slightly reflexed and curved, posterior angles acute, base 

 widely eraarginate; elytra about as long as the jironotum and half the head, dull ; 

 embolium shining, clothed with a sparse suberect pilosity, membrane reduced to a 

 mere strip ; abdomen considerably wider than the elytra, suboval ; legs with the 

 femora blackish-brown, tibiae slightly paler. Long., 2'5 mm. 



Capsina. 



Myrmecoris gracilis^ Sahib. (Ent. Mo. Mag., xxxix, p. 269). 



This interesting and striking addition to our fauna was captured 

 by Mr. E. A. Butler at Fleet, in Hampshire, on heathy ground, not far 

 from a nest of Lnsius niger. 



Myrmecoris may be known generically from Pithauus, the only British genus 

 which at all resembles it, by the elongate thorax, which is nearly as long as the 

 abdomen, exhibiting the |)ortion of the mesonotuin in front of the scutelhim, by the 

 longer face, which is longer than its width across tlie eyes, and by the less swollen 

 basal joint of the antenna?, as well as by having its thorax strongly constricted in 

 the middle and its abdomen at the base. 



It is a narrow black insect, much resembling an ant in form by the large head 

 and by the constrictions of the thorax and abdomen as mentioned above ; legs and 

 anteniiffi pale piceous, the latter darker on the apical half; elytra whitish at the 

 base and apex ; abdomen with the sides of the connexivum triangularly spotted 

 with white at the joints of the segments ; tibiae with very fine inconspicuous hair- 

 like spines on their inner side. Long., 4 — 5 ram. 



Megalocercea longicornie. Fall. = M. linearis, Fues. 



„ {Trigonotylus) brevipes, Jak. (Eiit. Mo. Mag., xxix, 



p. 110). 

 Introduced by Dr. O. M. Keuter on specimens taken by him on 

 Oulbiu ISands, near Forres, on P,^anima arenaria. Mr. Butler also 

 met with it at Lowestoft ; it is the variety which is mentioned in 

 " Hemiptera of the British Islands," but which has since been raised 

 to the rank of a species. 



According to Renter's table (loc. cit.) it differs from riificornis in being wider, 

 with the antennae paler and finely pilose, and having the 2nd joint almost longer
