The Lab 6.3 : In Growing : Stephen B. Nguyen, Wade Kavanaugh
No full text"Painter Stephen B. Nguyen and sculptor Wade Kavanaugh create collaborative installations using elements from their independent practice to address the uncertain territory between imagined and physical space. Audience, environment and space are considered as New York-based artists Nguyen and Kavanaugh transform the the LAB with layers of brown kraft paper that is reworked to create what they imagine as the texture and feeling of the inside of a giant Sequoia tree trunk. Previous collaborations using these same materials seemingly grow from the structures they inhabit, enveloping the viewer and redefining the parameters that define the viewers' experience within that space. It creates a space that our bodies would otherwise not occupy and that would only exist in our imaginations." -- Publisher's website

Mandible with prominent teeth, second and third teeth with inner side almost straight [second and third teeth with inner side produced with round margin], fourth tooth pointed apically. Antennal scape about 3.3× as long as its maximum width [about 3.7× as long as its maximum width]; flagellomere I about 1.8× as long as wide [about 1.5× as long as wide], flagellomeres II and III slightly longer than wide [flagellomere III as wide as long], flagellomere IV as wide as long, flagellomeres V–IX wider than long, terminal flagellomere small, slightly curved, 3.5× as long as its basal width, reaching to near base of flagellomere IX when folded [terminal flagellomere bullet-shaped, as long as its basal width] (Fig. 3).</p> <p>Mesosoma, metasoma (except tergum VII and sternum VII), and body sculpture as same as in female except clypeus with dense, small, deep punctures [clypeus with dense, large, flat-bottomed punctures, each bearing silver bristle, punctures at center larger than at sides, space between punctures larger than puncture diameter]. Tergum VII and sternum VII with some small and sparse punctures come between minute punctures.</p> <p> <i>Color</i>.
