segment fuscous and a|)ical third extended beyond apex of head, the 

 posterior lobe of the ])ronotuni is not so closely punctate and is 

 marked with two or three median longitudinal paler streaks; the hind 

 tibia are less bristly and the hind tarsus with basal segment relatively 

 longer, nearly three times as long as second and third segments 

 together. Specimens ]al»eled Lig. costalis in the collection of Mr. 

 Heidemann explains why this was recorded by Hanks as belonging 

 to this genus. 



Ligyrocoris depictus niw species. 



Very similar to and very closely related to L. diffnsus Uhl. Coloration of 

 body parts, antenna: and legs the same. The hcmielyira, however, arc almost 

 entirely dark castaneoiis brown within ; the base, entire costal margin and 

 much reduced inner apical spot stramineous-yellow, with no traces of trans- 

 verse postnudian costal fascia. The membrane is brown with a longitudinal 

 median streak and some of the veins basally pale. 



The antennae arc unusually long, with all of the segments except the basal 

 one relatively longer than '\r\ diffusus. The pronotum is differently shaped and 

 devoid of setse ; constricted well behind the middle, leaving the dull black 

 anterior lobe nearly twice as long and scarcely narrower than the posterior 

 lobe ; the width in front is suhe(|ual to the diameter at the constriction. The 

 number and arrangement of the spines on the fore femora is not distinctive. 

 Most fre(|uently the membrane does not reach the apex of the abdomen, in 

 other cases it is fully developed. 



Length 5-6 mm.
