METOPIINI 211 



not spinose, each elytron with a single basal fovea, no dorsal stria but with 

 a subentire, well-formed sutural stria; (9) five tergites with lateral margins 

 carinoid; (10) males with seven sternites and females with six sternites; (11) 

 posterior coxae widely separated. 



Genotype: Barrometopia quasimoda new species. 



Barrometopia quasimoda new species 



Holotype Male. Measurements: Head 0.3 (from distal margin of antennal 

 tubercle to occipito-cervical sulcus) x 0.3 through tempora; cervicum 0.053 

 mm.; pronotum 0.27 x 0.28 mm.; elytra 0.502 x 0.53 mm.; abdomen 0.23 x 0.47 

 mm.; length 1.4 mm.; width 0.53 mm. (PI. XVIII). 



Uniform light reddish-brown with yellow palpi; integument very lightly, 

 very sparesly and minutely granulate, strongly shining; the pubescence con- 

 spicuous, consisting of moderately long, moderately dense, flavous setae which 

 are bristling and erect, with their ends sharply recurved on head, pronotum 

 and elytra but more subdecumbent on abdomen. 



Head subpyriform, widest through tempora, narrowing rapidly anterior 

 of the eyes to form the prominent antennal tubercle which is T-shaped in 

 outline; tempora long (0.16 mm.) about half the head length and four times 

 the eye length; eyes small (0.04 x 0.04 mm.), circular, composed of 10 facets. 

 Vertex with a narrow moderately deep, longitudinal sulcus from the base of 

 the antennal tubercle to just posterior of the posterior eye margins; between 

 the eyes, and on either side of the posterior part of this longitudinal sulcus, 

 are two flavous, slightly elevated, quadrate, glabrous areas; each of these 

 quadrate areas is extended anteriorly to the base of the antennal tubercle in a 

 less elevated acute-triangular extension, and each of these triangular areas is 

 bounded mesially by a sharply limited, narrow sulcus so that the head anterior 

 of the eyes is trisulcate; two vertexal foveae placed on the posterior third of 

 vertex, each fovea nude, conspicuous and obliquely oval in shape, larger than 

 an ocular facet and in line with the lateral margin of the quadrate areas 

 noted above. 



Transverse occipito-cervical sulcus minutely, longitudinally sculptured; 

 rest of cervicum lightly alutaceous to glabrous. 



Mentum glabrous. Ventral surface of head tumid, with a weakly formed, 

 subquadrate depression at middle of base. Ventral surface of cervicum granu- 

 lated. 



Antennae eleven-segmented, subcontiguous, strongly geniculated; segment 

 I long (0.8 mm.), nearly as long as rest of antennae (1.0 mm.), the total 

 antennal length longer than body length, the first segment slightly contorted, 

 granulate, broader in basal third, narrowing to apex where it is dilated, with 

 a foveaform depression on the ventral face of this expanded apex; II, III 

 obconical (second 0.2 mm. long, third 0.1 mm. long) ; IV subobconical, shorter 

 than third; V as long as fourth, wider than fourth or sixth; VII as wide as
