than third on the oubital ncrvure. Third abscissa of radius longer than 

 first two together. 



Collected hy Oslar at Preseott, Arizona. 



5795 Hoplisoides clavatus n. sp. 



A small black compact species, almost entirely finely densely punctur- 

 ed and with very pale yellow narrow markings and subhyaline wings. 



Male: Length 6.5 mm. Pubescence fine, closely appressed; some 

 longer hairs about lower part of face. 



Hea^d large, subquadrate as viewed from al»ove, slightly broader than 

 the thorax. Inner orbits not at all emarginate above, strongly conver- 

 gent below, so much so that the clypeus appears abnormally extruded, 

 and the fac(^ has a dished appeaiance. Orbits below narrowly, scape 

 underneath, (dyp(ni« on the apical two-thirds except a pieeous blotch 

 at the middle, yellow. Mandibles entirely piceous. Flagellum elavate, 

 broadly paJ.e ferruginous underneath, narrowly above and funicular 

 article piceous. 



The furrow between rn'Oso and metapleurae is very unique, being 

 extremely broad without a deeper median groove, not carinately 

 rimmed at the sides, but sharply demarked below by a continuation 

 of the cairinate rim of the niesopleurae, and in the place of the 

 anterior rim, only the fine sharp groove of the suture; its two faces 

 are sharply rather coairisely striate. Upper aroa of inetanoum very 

 large, very coarsely obliquely rugose on either side of the foveolate 

 median groove which terminates in a long acutely pointed median 

 fovea situated entirely within the upper area. Posterior face rugose, 

 foveolate-rugose near the hind margin. The lateral shoulders of meta- 

 thorax are covered with a mat of long silvery white hair. The yellow 

 markings on thorax are a narrow line on pronotum, the tubercles, email 

 epots below the tegulae, and a narrow line near the hind margin of 

 scaitel. 



Abdomen not at all petiol.ate. Segments I-V with narrow apical 

 bands, the first medially emarginate, the others, suddenly broadened 

 laterally. Venter entirely black, shining, shagreened, with very few 

 punctures. The pygidium is black, somewhat narrowed just before the 

 ferruginous apex, the surface longitudinaJly rugoso-punctate. 



Legs black, fore and middle femora beneath at apex, and hind 

 tibiae posteriorly, yellow, tansi piceous. Middle and hind tibiae with 

 a considerable number of stont spines on posterior surface. Fore tarsi 

 only with greatly elongated spines on outside. 



Wings subhyalne, the nervures and stigma uniformly dark. 



Second cubital cell nearly the simie length as the third on the cubital 

 nervure. Third abscissa of the radius slightly longer than the first two 

 together.
