other species of this genus are injurious to cotton, especially 0. 

 hyalinipennis Costa (laetus Kirby), which is widely spread in 

 tropical Africa and Asia. Some of them seem to be spreading, 

 more and more, probably being transported by trading vessels. 

 I have received the Indian 0. bicolor Fieb., of which 0. heraldus 

 Dist. is a variety, from different places in Australia. 



The white costal margin behind the large subbasal spot of the 

 corium in 0. lugubris is sometimes very indistinct; and the 

 rostrum is variable in length, sometimes not reaching the base 

 of the venter, but occasionally extending almost to its middle. 



Horvath has rightly united the genus Maruthas Dist. with 

 Oxycarenus Fieb. As in so many similar cases Distant main- 

 tains the separateness of his genus, referring to the "structural 

 differences" pointed out in his description. These differences 

 are said to be "the length of the rostrum, the spinous anterior 

 femora and the membrane not reaching addominal apex." As 

 Oxycarenus is a well-known genus described by several authors, 

 including Distant himself, it is curious that he is unaware that 

 the anterior femora are spinous in all species of Oxycarenus; 

 that the rostrum, as pointed out by Stal, sometimes even reaches 

 the apex of the abdomen ; and that the membrane does not quite 

 reach the abdominal apex, and cannot be relied on even as a 

 specific character. 



Oxycarenus bicoloratus new name. 



For the New Caledonian 0. (M.) bicolor Dist., the name of 

 which is preoccupied, I propose the name Oxycarenus bicoloratus. 



(To be concluded.)
