Form: A short, broad and quite flattened species. Length about 3 

 mm. Vertex longer than in preceding members of Agallia group and 

 distinctly longer at middle than next to eyes. Pronotum twice wider 

 than long, transversely striated, especially on posterior two-thirds, with 

 anterior margin broadly rounded, posterior margin truncate or very 

 slightly conca.ve, lateral margins very short, humeral margins straight. 

 Elytra broad, little longer than abdomen in female, considerably longer 

 in some males. 



Color: Light grey, with markings varying from very light to very 

 dark. Vertex with two large black spots, broad median brown band and 

 brown lines next the eyes. Face with suture, six or seven pairs of 

 frontal arcs, and a median line on clypeus, brown. Pronotum with an 

 interrupted arc of six brown dashes parallel with anterior margin, and 

 with three longitudinal brown lines running caudad from the arc, the 

 median band with a light band in its middle. Elytra with a mottled 

 appearance, nervures brownish. 



External genitalia: Female, last ventraj segment over twice as wide as 

 long, posterior margin sinuate, appearing to have two small lobes sepa- 

 rated by a median notch; pygofers broad and exceeded by the ovipositor. 

 Male, valve short, about six times as wide as long, truncate, lateral mar- 

 gins strongly narrowed posteriorly; plates broad, tapering to truncated 

 tips, bases appearing constricted because enclosed by pygofers whose 

 tips, thickly set with coarse hairs, slightly exceed tips of plates. 



Male internal genitalia: Styles composed of cephalic club-shaped por- 

 tion with the clubs bent mesad and a caudal flat part with the inner 

 margin strongly serrate for its entire length and the latero-caudal corner 

 drawn out into a long stout point, the points for attachment of con- 

 nective very prominent; connective with broad, rounded base, slightly 

 concave on anterior margin, and with well developed stem; oedagus short 

 and stout, U-shaped, with arms short. Collar at base of anal tube 

 V-shaped with sides strongly divergent and appearing to be composed 

 of five segments. 



Distribution: This species seems to be more widely dis- 

 tributed in the state than any other of the Agallia group. The
