The single example in our collection is identical with the specimen labelled Atymna 
carinata in the Vienna Museum collection, and Dr. Goding has returned it to me as 
Cyrtosia discoidalis, Emmons. I have not myself seen a typical specimen of the last- 
mentioned insect. 
The specimen in the Vienna Museum is figured. 
3. Cyrtolobus virescens, sp. n. (Tab. IX. figg. 1, la.) 
Elongatus, angustatus, viridi-testaceus, capite subrugoso, remote punctato, pronoto fortius, haud profunde, 
- punctato, carinato, antice convexo, leviter depresso, dorso fere sequali, humeris vix prominulis, lateribus 
utrinque impressis, apice curvatim deflexo; tegminibus hyalinis, ad basin virescentibus, punctatis ; 
corpore subtus pedibusque totis testaceis. 
An elongate and narrow species, of a greenish-testaceous colour, perhaps bright green in life, with the 
pronotum subrugosely and rather strongly, but not deeply, punctured; shoulders scarcely prominent ; 
dorsum, if viewed from the side, almost even, carinate, slightly depressed in front, sides broadly impressed, 
apex rather long, deflexed ; tegmina hyaline, greenish and rather strongly punctured at the extreme base ; 
underside and legs testaceous. 
Long. 9 millim.; lat. int. hum. 34 millim. 
Hab. Mexico (Mus. Oxon.), Xucumanatlan in Guerrero 7000 feet (H. H. Smith). 
In the specimen from Xucumanatlan there are two very obscure lighter bands behind 
the middle and before the apex; but it is often almost impossible in the case of these 
greenish-testaceous species to determine what was the real colour in life. 
4, Cyrtolobus distinguendus, sp. n. 
Testaceus, castaneo-brunneo obscure variegatus, pronoto sat fortiter denseque punctato, dorso elevato, utrinque 
impresso, a latere viso equaliter rotundato a fronte metopidii usque ad pone medium, ibi sinuato, depresso, 
et in apicem haud longum paullo deflexum extenso; tegminibus prothoracis apicem multo superantibus, 
totis hyalinis ; corpore subtus pedibusque dilute testaceis. 
Slightly smaller than the preceding species, testaceous, obscurely variegated with castaneous or rufous- 
brown; pronotum closely and strongly, and in parts subrugosely, punctured, impressed at the sides ; 
‘dorsum carinate, evenly rounded from just above the head to behind the middle, and then considerably 
depressed and sinuate and produced into a rather short apex; tegmina entirely hyaline; underside and 
legs light testaceous. 
Long. cum tegm. 83 millim.; lat. int. hum. 3} millim. 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
One female specimen.
