506 PHYTOPHAGA. 



pattern than the description. In a single small specimen, probably a male, the suture 

 is entirely black to the apex, the pattern of the elytra therefore closely resembling that 

 of D. morosa, from which, however, the flavous femora will distinguish it. The thorax 

 is without impressions; and the antennae in the male are distinctly longer than in any 

 of the preceding species, extending nearly to the apex of the elytra. 



b. My tr a flavous, with transverse black or blue bands. 



10. Diabrotica paradoxa. (Tab. XXIX. fig. 13.) 



Fulvous, the head, tibise, tarsi, and breast black ; thorax with two small impressions ; elytra testaceous, a 

 narrow transverse band at the base, another at the middle, and a large subquadrate or oval spot on each 

 near the apex, black. 



Length 3 lines. 



Head, labrum, and palpi black, the space between the antennae rather deeply foveolate ; antennae half the 

 length of the body, the second and third joints short and equal, the basal joints more or less fulvous, the 

 following joints piceous or black, the last three testaceous, with the apex of the terminal joint fuscous ; 

 thorax subquadrate (shaped as in D. tessellata), impunctate, the surface impressed on each side with a 

 small (more or less distinct) fovea : scutellum fulvous or piceous ; elytra very finely punctured, with a 

 more or less distinct longitudinal depression below the shoulders, the two anterior black bands rather 

 closely placed, the posterior margin of the basal band irregularly notched and sometimes confluent at the 

 sides with the second band, the space between these bands and the large apical spot broader than that 

 between the two anterior bands ; femora and abdomen fulvous, the tibiae and tarsi black. 



Hob. Beitish Honduras, R Hondo (Blancaneaux) ; Guatemala, Teleman, Chacoj, 

 and Panima in Vera Paz (Champion), Yzabal (Salle). 



The two bands of the elytra in this species are of rather regular shape and very 

 slightly curved, but neither they nor the large apical spot extend quite to the lateral 

 or posterior margins ; the black (not blue) colour of these markings, in connection with 

 the black tibiae, will separate D. paradoxa from any of the preceding species and their 

 varieties. An example from Chacoj is figured. 



11. Diabrotica albo-signata. (Tab. XXIX. fig. 14.) 



Diabrotica albosignata, Ealy, Trans. Ent. Soc. Lond. 1886, p. 453 1 . 



Hab. Guatemala 1 , Cubilguitz, Coban, San Joaquin, Purula, Sinanja, Chacoj (Cham- 

 pion); Mcaeagua, Granada (Salle). 



D. albo-signata is separated from D. paradoxa by the equally divided elytral 

 black bands, and by the black apices of the elytra forming a small triangular spot : in 

 none of the specimens I have for examination does the posterior or last elytral 

 black band assume the shape of an oval or square spot, but the two anterior bands are 

 sometimes (as is occasionally the case in D. paradoxa) more or less connected, and the 

 legs are occasionally entirely black ; in other respects there is no difference in the two 

 insects. As both were obtained partly in the same localities, it is doubtful whether 

 they represent distinct forms or varieties of one only. The Nicaraguan example is 

 figured.
