PHYTOPHAGA. 



Three or four almost similarly marked species have been described by Lacordaire and 

 Kollar ; and it is very difficult to come to certain conclusions as regards their specific 

 value, it being necessary to compare all the types. Of the present species, to which I 

 refer a single specimen from M. Salle's collection, Lacordaire says nothing in regard to 

 the length or width of the thorax, which I consider of importance in these similarly 

 coloured insects ; but the description agrees in general with the specimen before me ; 

 the elytral lines of which Lacordaire speaks may be seen more distinctly if the insect is 

 held sideways, in other positions these lines are almost obsolete and very difficult to 

 follow. 



27. Chlamys gysseleni. 



Chlamys gysseleni, Koll. Mon. Chlamyd. p. 43, t. 2. fig. 46 1 ; Lacord. Mon. p. 769 2 . 

 Chlamys granulata, Klug, Ent. Mon. p. 146, t. 10. fig. 3. 



Hab. Mexico, Cordova, San Andres, LaParada, Juquila {Salle); Guatemala {SalU). — 

 Brazil, Rio de Janeiro * 2 . 



I cannot but refer the specimens from M. Salle's collection to the Brazilian species, 

 allowing of course for variations natural in countries so far removed : the elytral costae 

 in the Guatemalan insect are not very distinct ; and the elytra are very irregularly 

 foveolate punctate ; but in general character I cannot find sufficient ground for separating 

 the two forms. The specimens from Mexico show, again, some difference in the sculp- 

 turing of their elytra; so that almost each of them might constitute a species if one 

 drew the line too close ; but, on the whole, the same characters are visible in all of them. 



28. Chlamys hypocrita. (Tab. IV. fig. 21.)

Hab. Mexico', Cordova {Salle), Yucatan ; British Honduras. — Colombia! 



This species is not easy to distinguish from several others belonging to the same 

 group described by Lacordaire. A specimen from Honduras contained in the Berlin 

 Museum is figured here; two others, contained in the collection of M. Salle, do not 

 quite agree with the Berlin specimen ; the elytra are much more deeply sculptured 

 and punctate, the raised costse much more distinct, in which respect they resemble 

 C. gysseleni, Lac, which species, however, varies in other respect; I do not think it 

 therefore advisable to make the above-named specimens new species unless more material 

 should necessitate it, but consider them varieties of C. hypocrita. 



29. Chlamys scabiosa.
