Description: A pale almost uniformly gray color in females, while more mottled with brown on the metopidium and crest in males. The pronotum is long, slender acute, and the crest is long and low; the anterior lobe of the crest is an acute pyramid, distinctly one-half higher than the horizontal posterior lobe. The posterior margin slopes into the pronotum. The anterior and posterior lobes are inflated, and the humeral angles of the crest are strongly olbique and almost twice longer than wide, with bluntly rounding apices. Males are 8 mm long, while females are 10 mm long, 7 mm wide, and 4.5 mm high. (Kopp & Yonke, 1974)
