In attempting to correct the description of this species, ad- 

 mittedly incorrect in some respects, Girault has himself erred. 

 A careful examination of slide mounts of the antennae from 

 paratype specimens of both sexes shows the following to be the 

 facts: The female antennae have four ring-joints, three funicle 

 joints and a three jointed club; the first three ring-joints are very 

 small transverse and closely jointed together so that in a dry 

 mounted specimen they appear as one very small joint; the fourth 

 ring-joint is subquadrate, being considerably larger than the 

 three preceding ring-joints combined; the funicle joints are as 

 indicated in the original description; the club is about equal in 

 length to the two preceding funicle joints, the three joints distinct 

 in a balsam mounted specimen but not well separated, the sutures 

 consisting of mere shallow grooves. The male antennae have- 

 three small transverse ring-joints (not four as stated by Girault 

 The funicle appears to be 5-jointed and the club 2-jointed, the 

 funicle joints each with a whorl of long hairs. In the original 

 description the statement was made that "the funicle is really but 

 3-jointed, the first ring-joint being greatly elongate and the 

 basal joint of the club resembling the funicle joints." This 

 statement is wrong since it is the last ring- joint, not the first, 

 which is elongate. The apparent fifth funicle joint is believed 

 to be merely the basal joint of club more than usually detached 

 and modified to resemble a funicle joint. Only in this manner 

 can the antennae of the male and female be homologized. 



Ceratoneura petiolata Ashmead. 



Examination of a slide mount of the female antenna of this 

 species shows it to have apparently four ring-joints similar to 

 those in pretiosa, vis., the first three short and transverse while 

 the fourth is large and subquadrate; the three basal ring-joints 

 are even more closely joined and indistinct than in pretiosa; the 

 funicle consists of three subequal joints each approximately one 

 and one-half times as long as thick, the middle joint very slightly 

 the longest in the specimen examined ; the club is shorter than the 

 two preceding funicle joints combined, indistinctly o-jointed, UK 

 sutures, especially the last, very indistinct. The male funicle i> 

 5-jointed and club 2-jointed; first funicle joint only slightly 

 longer than broad and much shorter than the second which is 

 fully twice as long as thick; following joints of funicle decreasing 

 slightly in length toward the apex; club shorter than the two 

 preceding funicle joints combined, its first joint much longer than 

 the second, all funicle joints with a basal whorl of long hairs.
