SOME GUATEMALAN ORTHOPTERA, WITH DESCRIPTIONS 
OF FIVE NEW SPECIES. 
Lawrence Bruner. 
The twenty-eight species of Orthoptera reported in this paper 
were collected during the winter of 1905 by James S. Hine, 
of Columbus, O., who referred them to the writer for determina¬ 
tion. Although the collection is but a small one it is very inter¬ 
esting since it contains specimens of at least four species -which 
appear to be new to science and others that materially extend 
the range of known forms. One of the new species, Cornops 
scudderi, adds a South American genus hitherto not reported 
for North America. 
Family Blattidae, 
1. Pseudophyllodromia venosa Sauss. This insect is represented by a 
single specimen taken at Mazatenago, February 3. 
2. Blabera trapezoidea Burm. A single male of this large cockroach 
was collected at Santa Lucia February 1. 
Family Mantidae. 
3. Stagmomantis dimidiata Burm. The species is represented by a fine 
male which was captured March 5, at Puerto Barrios. ’ A fe¬ 
male nymph that was taken at San Jose on February 5 is also 
referred here. 
Family Gryllidae. 
4. Oecanthus nigricornis Walk.(?) The collection contains two males of a 
tree-cricket which were taken on February 7, at Amatitlan. One 
of these has the greater portion of the antennae pale testaceous 
instead of black, as described by Walker. Both, however, lack 
the black lines or dots on the two basal antennal joints, thereby 
agreeing with the insect that Henri de Saussure takes to be Walk¬ 
er’s nigricornis, but perhaps erroneously, as the types of Walker's 
insect came from Illinois. 
5. Oecanthus varicornis Walk.(?) A single female with the two basal 
antennal joints unifasiate with black, but otherwise agree¬ 
ing very closely with the preceding, is referred here. It was taken 
at the same time and place with them. 
(i. Parcecanthus aztecus Sauss. I he single specimen, a female, of this 
species comes from Gualan where it was captured on March 3. 
Family Locustidae. 
- Hormilia tolteca Sauss. Three specimens, two males and a female, 
are at hand from Mazatenango. They were collected February 3 ! 
N Orophus conspersus Brunn A single female of this species was taken 
at I\ azatenango on February 8. 
Orophus lessellatus Sauss. A single female taken February 2, is 
labelled as coming from Santa Lucia. 
10. Eriolus consobrinus Sauss. et Piet. On February 1, a female of this 
species was taken at Santa Lucia. 
1 1 Thysiius infirmus Sauss. et Piet. The collection contains a pair of 
ti is delicate species. They come from Mazatenango, and were 
caj tured February 3. 
1-’. Idiarthron atrispinum Stal The insect before me is a little large as 
compared with the measurements given in Brunner’s monograph, 
of the Pseudophyllidae, but it agrees in other respects with Stal’s 
Meroucidius otrispinosus. It comes from Santa Lucia, where it 
was taken February 1.
