356 NITIDULIDZ. 
evidently pallid, and besides this differs also in sculpture. The thorax is more finely 
and sparingly punctate, so that there is a greater contrast between the punctuation on 
it and that on the head. The elytra have their series of punctures irregular but not 
duplicate, and only a very distant interstitial punctuation. 
Mr. Champion procured a small series of this species; the specimens exhibit very 
little variation. 
3. Strongylus chiriquensis, sp. n. 
Rotundato-ovalis, convexus, nitidissimus, rufo-piceus, antennarum clava nigra; elytris obsolete seriatim 
punctatis. 
Long, 43 millim. 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers); Panama, Volcan de 
Chiriqui 3000 to 4000 feet (Champion). 
This species is distinguished from 8. lateralis by the uniform, more dilute colour, 
and by the more obsolete sculpture of the elytra. In other respects the two appear to 
be excessively similar. One example only from each locality. 
4. Strongylus camptoides. 
Strongylus camptoides, Reitter, Verh. Ver. Briinn, xii. 1, p. 1287. 
Hab. Mexico (Mus. Vindob.+), Cordova (Sallé). 
Very close indeed to S. lateralis and S. wnicolor; but the pygidium is red, and the 
under surface dark red or piceous. I have seen only two specimens. 
5. Strongylus mollis, sp. n. 
Rotundato-ovalis, convexus, nitidus, piceo-testaceus, supra piceus, prothoracis lateribus, antennis pedibusque 
testaceis, antennarum clava fusca. 
Long. 43 millim. 
Hab. Mexico, Jalapa (MZ. Trujillo). 
Though different in colour from S. lateralis this insect is very closely allied thereto, 
and may possibly be an immature colour-variety of that species; but I think it more 
likely to prove distinct, the shape being broader and the prosternum more obsoletely 
carinate: in punctuation the two are very similar. Three specimens. One of the 
examples appears to be mature; and in it the colour of the lower surface is flavescent, 
with the middle of the body piceous. 
6. Strongylus sequalis, sp. n. 
Rotundatus, valde convexus, subtus dilute piceus, supra nigerrimus, antennarum basi rufa. 
Long. 3 millim. 
Hab. Mexico, Cordova (Sailé); Panama, Volcan de Chiriqui 3000 feet ( Champion).
