Sfcuocmiiits ( ?) sacchanvoriis, Van Duzee 1897 Bull. Buffalo 

 Soc. V, 232. 



Mr. Ballou of the West Indian Dep. of Agriculture has re- 

 cently sent me specimens of this in all stages, enabling me to con- 

 firm Van Duzee's doubtful reference to Stcnocranus, but too late 

 to present a detailed study in this paper. The egg-slits are much 

 more profusely covered with waxy substance than in Pcrkinsi.ila. 

 approaching more, so my colleague Mr. Swezey informs me, to 

 the condition of certain North American forms. The delicate 

 pale green, immaculate adult cannot be mistaken for any other 

 species ; the head in profile is long and acute anteriorly. It is 

 stated by Ballou (1905 West Indian Bull., VI, 41) to be of httle 

 importance as a pest in the Antilles, though formerly, some 70 

 years ago, it was, according to Westwood, Johnstone and others, 

 exceedingly destructive in certain of the islands. 



Hadeocidpha.v, gen. nov. 



Allied to Stciiocraiiiis l)ut difTering by the form of the head, the 

 venation, etc. 



Dorsally the head is elongate, subquadrangular, extending 

 well beyond the apical margin of the eyes; near the anterior mar- 

 gin of the eyes (but a little below) the lateral keels bifurcate at 

 an acute angle, 'the inner keels meeting acuminately a little be- 

 yond the apex o,*^ the vertex; the latter is keeled medianly as far 

 as the apical margin (dorsally) of the eyes, where it forks on each 

 side at an obtuse angle meeting the inner forks of the lateral 

 keels. Head much narrower than the pronotum. Eyes longer 

 than broad, suboblic|ue. Ventrally, the frons is somewhat nar- 

 row, widening a little apical of the eyes ; lateral keels sinuate ; 

 these, with the median keel, strongly marked. No forking visi- 

 ble on frons. Antennae short. Clypeus tricarinate. Pronotum 

 tricarinate, laterally straightly divergent, ending just before pos- 

 terior margin. Scutellum tricarinate. Tegmina with about 9 

 apical areas, the base of the fourth not reaching as far basal as 

 that of the third, the third not as far as the second, the second 

 not as far as the first, the first not as far as the fifth. Posterior 

 tibiae and tarsi about equally long. 



I. pluto, sp. nov. 



Blackish piceous ; antennae and legs testaceous. Tegmina 

 dark smoky, first and second apical cells and apex of costal cell.
