PROMETOPIA.—PLATYCHORA. 317 
Closely resembling P. equalis, but smaller, with a more scanty and coarse pubescence, 
and the apices of the elytra rounded, the pygidium being thus nearly covered. 
4. Prometopia cryptarchoides. 
Prometopia cryptarchoides, Reitter, Verh. Ver. Briinn, xii. 1, p. 51°. 
Hab. Mexico 1, Parada (Sallé); Guatemata, Las Mercedes, Guatemala city, Zapote 
(Champion); Panama, Volcan de Chiriqui (Champion). 
This insect has a fine and scanty pubescence mixed with the suberect coarse sete of 
the thorax and elytra. 
It is apparently the least rare of the Prometopie found in our region; we have 
received nineteen examples. 
5. Prometopia soronioides, sp. n. (Tab. X. fig. 10.) 
Oblongo-ovalis, minus depressa, fusco-testacea, pubescens, setulisque albidis micantibus adspersa ; corpore 
limbo testaceo, elytris pone basin et ante apicem ferrugineo-quadriguttatis ; prothorace lateribus rotun- 
datis, fortiter explanatis. 
Long. 34-4 millim. 
Hab. Guatemata, San Geronimo, Purula (Champion); Panama, Volcan de Chiriqui 
(Champion). 
This species is very distinct by the comparatively small eyes, the less elongate head, 
and the much shorter mentum; in its general shape and clothing it is more like 
Soronia or Lobiopa. Antenne red, with the club fuscous. Thorax with the sides 
rounded, broadly explanate, the hind angles not acute, rather coarsely but oosoletely 
punctate, hispid. Elytra sparingly punctate, with a rough setosity which is gleaming- 
white on the pale marks, and with some distant coarser white sete serially arranged. 
P. soronioides bears a great superficial resemblance to Lepiarcha omositoides.
