Family Acridiidae. 
13. Paratetix mexicanus Sauss. The collection contains a single male 
specimen of this species. It was taken on March 8, at Puerto 
Barrios. 
14. Tettigidea chichimeca Sauss. A single female specimen represents 
the present species so far as the collection now before me is con¬ 
cerned. It also comes from Puerto Barrios, where it was taken 
on the same date as the last. 
15. Amblytropidia costaricensis Bruner. The only representative of this 
rather common genus in tropical America is a single specimen of 
A. costaricensis. It was taken February 7, at Amatitlan. 
16. Orphula guatemalae n. sp. Most nearly related to O. azteca Saussure, 
but differing from it in its smaller size and slenderer form. It 
differs also in the female by having a more uniform color—the 
tegmina maculations are fewer and smaller, and the basal joints 
of the antennae are less depressed. The hind femora of both sexes 
are also shorter and more graceful. The valves of the ovipositor 
are shorter and slenderer than in azteca or meridionalis. In its 
general color the present species varies from pale testaceo-fer- 
ruginous to dark brown in the female, while the males have the 
dorsum of occiput, pronotum and tegmina testaceous or green. 
In the male the sides of the head, pronotum, pleura and costal 
and discal field of tegmina are unspotted brown; the lateral pro- 
notal carinae are edged below with dark piceous in both sexes. 
Abdomen venter and face pale testaceous, the legs a little darker 
and somewhat infuscated at the knees. Sides of basal abdominal 
segments of male more or less piceous. 
Length of body, $ , 15.5 mm., 9 . 22.5 mm.; of pronotum, 
$ , 3 mm., 9 . 4 mm.; of tegmina, £ , 13,25 mm., 9 , 17 mm.; 
of hind femora, $ , 9.5 mm., 9 , 12.25 mm. 
Habitat. The types,male and female, come from Santa Lucia 
where they were collected February 1. The collection also con¬ 
tains an additional female from the same locality and a pair from 
Mazatenango, February 3. 
The following table will show the realtionship of the species: 
Synoptic Table of the Species of Orphula. 
Al. Fastigium of the vertex with its antero-lateral egdes de¬ 
cidedly rounded. Basal joints of antennae greatly depressed. 
Lateral carinae of the pronotum only gently divergent on the 
hind lobe. pagana Stal. 
A2. Fastigium of the vertex with its anteor-lateral edges nearly 
ly straight. Basal joints of the antennae only gently de¬ 
pressed. Lateral carinae of the pronotum strongly diver¬ 
gent on the hind lobe. 
b 1 . Lateral carinae of the anterior lobe of the pronotum 
parallel (Costa Rica) meridionalis Bruner 
b 2 . Lateral crainae of the anterior lobe of the pronotum 
plainly divergent. 
c 1 . Larger and more robust (Mexico southerly) azteca Sauss 
c 2 . Smaller and rather slender (Guatemala) 
guatemalae n. sp. 
17. Orphulella arctata Walk.(?) There are four specimens, 1 female and 
3 males, of a locust that are doubtfully referred to Walker’s 
arctata. They come from San Jose, where they were taken on 
February 5. 
18. Orphulella meridionalis Bruner. One male and one female, Puerto 
Barrios, March 3.
