ADDITIONS TO THE NEARCTIC MELOIDAE (COLEOP.) 1

Among specimens sent for determination by several institutions 
and collectors are three striking additions to our fauna, which are 
described below. 
Epicauta cicatrix sp. n. 
Figure 5 
This, the thirteenth member of the caviceps-g roup, is the only 
one of the group thus far known from the Big Bend region. It can 
be distinguished from the other members, and from all other 
Nearctic and Neotropical members of Epicauta , by the form of the 
second antennal segment (see fig. 5). 
Length: 8 to 12 mm. Black, moderately densely clothed with 
cinereous to yellow-cinereous pubescence, except for the black 
markings at the base of the elytra and on the abdomen which are 
characteristic of the group, and a partially denuded spot on the 
temporal angles of the head. 
Head broad, 2/5 broader across the eyes than from vertex to 
clypeus, tapering from just behind the eyes to the broadly rounded 
temporal angles. Surface moderately densely punctured and strong- 
ly microreticulate, appearing fairly shiny. Median impressed line 
narrowly denuded, distinct down to the level of the eyes. Antennal 
calluses small, denuded, shiny. Eyes prominent, slightly oblique 
but unmodified, 3/5 as wide as high, as seen from side, with a nar- 
row denuded zone surrounding them. Pubescence short on top of 
head, very short and fine, black on the patch on the temporal angles. 
Rest of head with rather coarse pubescence. 
Antennae tapering gradually, with the intermediate segments 
stouter and the apical segments more slender in the $ than in the 
$ . $ antennae slightly more than three times as long as anterior 
tibia; segment I stout, reaching l/4 across eye; II 2/3 as long as I, 
posteriorly flattened and smooth, the base of the flattened area
