Porter — Mesostenines 
45 
notum: epomia strong in scrobe and reaching far dorsad onto the 
moderately swollen humeral margin of pronotum, where it forms 
a carinate elevation. Mesoscutum: shining with abundant coarse, 
medium-sized punctures which are mostly subadjacent to a little 
sparser; notauli sharp and narrow, reaching about 2/3 the length 
of mesoscutum. Scutellum: gently convex. Mesopleuron: prepectus 
opposite lower hind corner of pronotum with a long ridge that ex- 
tends 2/3 or more the distance veritrad to prepectal carina; surface 
between prepectal carina and speculum with strong oblique wrink- 
ling that on lower 1/2 becomes only gradually a little weaker and 
mingled with large but mostly obscure punctures; mesopleural su- 
ture grossly foveolate on lower 1/2. Lower metapleuron: with 
coarse oblique wrinkling that becomes more irregular dorsad and 
has only obscure intercalated punctures; juxta-coxal carina trace- 
able for about basal 0.5 of metapleuron. Front tibia: moderately 
inflated. Hind trochantellus: 0.36 as long as trochanter in dorsal 
view. Third hind tarsomere: in addition to apical spines with four 
longitudinal rows of strong spines numbering about 15 in all. Pro- 
podeum: spiracle 1.9 as long as wide; cristae strongly projecting 
ligulate, about 2.0 as long as wide at base, the apical trans-carina 
absent between them; dorsal face behind basal trans-carina with 
strong irregular wrinkling and puncto-reticulation but without dis- 
crete punctures; apical face almost uniformly with strong and quite 
regular transverse wrinkling. First gastric tergite : postpetiole 1.5 as 
wide at apex as long from spiracle to apex; in profile pyramidally 
elevated above spiracle. Second gastric tergite: mostly mat with 
fine micro-reticulation and on about basal 2/3 with numerous shal- 
low, medium-sized punctures separated in general by about 1. 0-2.0 
their diameters. Ovipositor: sheathed portion 0.46 as long as fore 
wing; tip 0.2 as high at nodus as long from nodus to apex, its pro- 
file between nodus and apex only slightly convex. 
MALE: Unknown. 
specimens EXAMINED: 2 females, USA {Texas: Hidalgo County, 
Bentsen Rio Grande Valley State Park, 29 XII ’76, C. C. Porter); 
PANAMA {Chiriqui: Valley of the Clouds, 17 III ’60, K. W. Brown). 
(Porter, Townes). 
DISCUSSION: This is the first record of lamentaria for the United 
States. The species has been cited previously only from Costa Rica, 
Guatemala, and Panama. 
A homotype from Panama, loaned by H. K. Townes, is un-
