of large shallow punctures placed behind transverse wrinkles, hardly 

 farther apart than the punctures of the striae. Length 2.5-3 mm - ; width 

 1. 2-1. 5 mm. 



Type $ and 9 , also 2 cotype S and 2 cotype 9 , No. 10036, 

 U. S. N. M.; 4 cotype £ and 4 cotype 9 remain in collection 

 of Cotton Boll Weevil Investigation. 



These specimens were all bred from Xanthoxylum berries 

 collected by A. C. Morgan, at Runge, Texas, May 9, 1906, 

 and Beeville, Texas, May 8, 1906. 



Parasites. 



Large numbers of Sigalphus zygobaridis Cwfd. were bred 

 from this weevil. The weevil larva carries the parasites under 

 ground, evidently internally, and after forming its earthen cell 

 the parasite devours it and spins a yellowish cocoon. The 

 parasites come out just before the weevils. 



Two or three Catolaccus incertus Ashm. were bred from the 

 berries, where they evidently kill the weevil larvae and pre- 

 vent their entering the ground. 



ZT60BAROIDES n. gen. 



The beak is strongly tumid at the base in both sexes, 

 although the tumidity is more pronounced and shorter in the 

 female. Beyond the tumid portion, the beak of the female is 

 slender, very smooth, and very sparsely punctate, while in the 

 male it is a little stouter, longitudinally ridged and strongly 

 punctate. The antennae are inserted in the male just behind 

 the basal one-fourth, and in the female at less than one-eighth 

 the length of the beak ; the scrobes are almost inferior and 

 reach the eyes ; the scape almost reaches the eye, in the 

 female being hardly more than spherical. The first and sec- 

 ond funicular joints are both elongate and longer than the five 

 following joints. 



The type of the genus is Zygobaroide's schwarzi. 



Zyyobaroides schwarzi n. sp. — More robust than Zygobaris xanthoxyli, 

 rhomboidal, moderately convex, slightly shining, dark reddish-brown ; 

 integuments subglabrous, the vestiture white, consisting of very mjnute 

 and sparse setiform squamules, with larger linear scales beneath. Beak 

 long and slender, almost straight in female beyond basal tumidity, only 

 slightly curved in male, strongly tumid at base, with the constriction dis- 

 tinct ; only sparsely punctate in female, but densely punctured and 

 ridged in male beyond tumidity ; tumidity in both sexes strongly punc-
