Description. — C’innamon brown, with extensive paler and darker areas; 
antennae darker toward apex; pronotuin dark on anterior lobe except carinae; 
jiostero-lateral areas more or less broadlj' jiale, as a rule; basal expansion of 
eoriuni and sometimes the veins, ajiex of scutellum and usually margins 
toward base, jiosterior angles of eonnexival segments and sometimes their 
posterior margins, and inner margins ol genital lobes, pale yellowish; mem- 
brane more or less distinctly maculated, the veins white; legs ami ventral 
surface rather dark, with variable indefinite jiale areas. 
Structure similar to that ot prohoscideus, excejit as follows: Head but 
slightly longer than pronotuin (32 to 29); antennae (fig. 23c) as long as head 
and ])ronotum together, length of the second segment almost ecpial to head 
width including both eyes, rather more distinctly enlarged at apex; rostrum 
extending lieyond middle of mesosternum. Pronotuin (fig. 23d) longer, the 
antero-lateral margins less strongly oblique and with coarser ami more ir- 
regular teeth; disc anteriorly very strongly convex, with a narrow dejiression 
lietween median carinae; intermediate carinae extending a little farther 
forward, the lateral jiair shorter. Scutellum obcordate, liroadly rounded at 
apex, sides generally distinctly sinuate. Basal expansions ot corium elong- 
ate, not evenly rounded, strongly reflexed. 
cf (fig. 23b). rdfth ventral segment distinctly shorter than sixth (10 to 
13); genital segment moderately convex, very short, the lobes short, with 
rounded apical margins; abdomen broailly oval, sides rather strongly eremite. 
Length, 0.4 to 0.0 mm. 
9 (fig. 23a). Dorsal genital segment one-half as long as broad; anterior 
margin less than a semicircle; iiosterior margin slightly curved, truncate 
.at middle; abdomen narrowly oval, iiointed posteriorly, the margins almost 
entire. Length, 7.3 to 7.5 mm.

fornia) in California Academy of Sciences and Van Diizee’s col- 
lections. 
This form is distinguished hy the non-annulate antennae, an- 
teriorly elevated ]tronotum, and the male and female genitalic 
traits. With the three [^receding species it is best described by 
comjiarison with pt ohoscideus, to avoiil the re]tetition of identical 
statements; the five are closely related but sufficiently distinct 
spi'cies and can be recognized without difficulty liy th(' critiuda 
(‘m])loyed in tlu' table of spi'cii's.
