principal sulcus, uioi'e distinct and sharp on the nietazona; median 

 carina porcurrent. considerably and evenly elevated, subcristate, cut 

 by one sulcus only: transverse sulci cutting the lateral carinte and well 

 developed on the lateral lobes. Interspace between the inesosternal 

 loV)es half as 1)road a(>ain as lono-, of metasternal lobes quadrate. 

 Teoniina moderately slender, intercalary vein well developed and api- 

 cally nearer the median than the ulnar vein, color l)rownish with a 

 large, lioht-gray rectangular spot on the costal artea just beyond the 

 humeral angle and a trace of the same color ])efore the angle and also 

 beyond the costal spot; the lower portion of the tip is transparent 

 membraneous, and the whole elytra is marked with darker l)lotches. 

 Wings broad, about two-thirds as broad as long; l)asal half, oi- a little 

 more, vellovv, followed by a moderately broad fuscous band which fails 

 to reach the anal angle below, interrupted narrowly at the first anal 

 vein and sending a taniia about half way to the base; beyond the fus- 

 cous band the wing is transparent with fuscous veins and with the 

 apex again becoming infuscated; stigma fuscous. Legs moderately 

 blender, fore and middle pairs brownish mottled lightly with fuscous: 

 postei'ior femora with two black l)ars across the dorsal surface, scarcely 

 extending across the brownish outer face, which has a pregenicular 

 ashy ])and; inner face black with a ])road pregenicular light band; 

 geniculations black on the inner side, fuscous on the outer: hind tihite 

 blue with a light-colored basal l)and: spines black to the base, nine to

 nmi., posterior femora 10 mm., greatest width of elvtra -4 mm., wing 

 11 mm. 



Type.— 0<ii. No. 8261, U.S.N.M. 



I have also a female taken by Oslar at All)uquerque, New Mexico, 

 without date. It is like the male, except the pronotum is somewhat 

 more rugose and the tips of the wings are less infuscated. It meas- 

 ures as follows: Length 22 mm., antennae 7.5 mm., pronotum 5 mm., 

 elytra 23 mm., greatest width of elytra 4 mm., of wings 11.5 mm. 



Professor Bruner says this is near to, but distinct from, L. <j!hhosii.s. 

 He also compared it with feJlepidiifi. and punetatus and found it differ- 

 ent. The L. hoscanu^! of Rehn has also been seen. 



The insect recorded from New Mexico Iw Scudder and Cockerell" 

 as Lactista 2)eUe2)idus is Tomonotus astecus.^ as determined l»y carefid 

 comparison of those specimens in the Scudder collection with typical 

 aztecus from Texaa identified by Bruner.
