Genus 21. GILVA. 
The description of this genus in page 141 is defective, and the fol- 
lowing may be substituted. 
Corpus ellipticum, convexum, nitens, punctatum. Caput lateribus 
anticis subreflexis, lobis lateralibus lobum medium vix superantibus. Oculi 
magni, extensi. Rostrum validum, coxas intermedias atlingens. Antenne 
graciles, corpore breviores; articulus lus brevissimus; 2us compressus ; 
4us 30 5oque longior. Thoracis auguli postici extensi, non acuminati. 
Scutellum apice rotundatum. Pedes robusti, setosi; tibie sulcate ; tibie 
antice apices versus subdilatate. 
Body elliptical, convex, shining, rather largely and thinly punctured. 
Head much shorter than the thorax, and hardly one-third of its breadth, 
slightly reflexed on each side in front; lateral lobes hardly extending be- 
yond the middle lobe. Eyes large, prominent. Rostrum stout, extending 
to the middle coxe. Antenne slender, minutely pubescent, much more than 
half the length of the body; first joint very short; second flat; third as 
long as the second ; fourth much longer than the third; fifth shorter than 
the fourth. Thorax with a very slight transverse furrow near the fore 
border; hind angles prominent, but without spines. Scutellum rounded

dilated towards the tips. 
The spines of the thorax and the ventral spine of Hoploxys distin- 
guish it from this genus.
